2. find the GCF and LCM of 21 and 56
Answer:
What is the GCF of 21 and 56?
The GCF of 21 and 56 is 7.
What is the LCM of 21 and 56?
The LCM of 21 and 56 is 168.
Step-by-step explanation:
Steps to find GCF
Find the prime factorization of 21
21 = 3 × 7
Find the prime factorization of 56
56 = 2 × 2 × 2 × 7
To find the GCF, multiply all the prime factors common to both numbers:
Therefore, GCF = 7
Steps to find LCM
Find the prime factorization of 21
21 = 3 × 7
Find the prime factorization of 56
56 = 2 × 2 × 2 × 7
Multiply each factor the greater number of times it occurs in steps or above to find the LCM:
LCM = 2 × 2 × 2 × 3 × 7
LCM = 168

18. dind the GCF and LCM of each number using any of the methods.25 and 7535 and 4527 and 3621 and 5654 and 72
Answer:
25 and 75= If the LCM of 75 and 25 is 75, Find its GCF.
If the LCM of 75 and 25 is 75, Find its GCF.Therefore, the greatest common factor (GCF) = 1875/75 = 25.
35 and 45= GCF of 35 and 45 Examples
GCF of 35 and 45 ExamplesTherefore, the greatest common factor of 35 and 45 is 5. Example 2: The product of two numbers is 1575. If their GCF is 5, what is their LCM? Therefore, the LCM is 315.
27 and 36= Therefore, the LCM of 27 and 36 is 108. Example 2: Verify the relationship between GCF and LCM of 27 and 36. Hence, verified. Example 3: The GCD and LCM of two numbers are 9 and 108 respectively.
21 and 56= LCM of 21 and 56 by Prime Factorization
LCM of 21 and 56 by Prime FactorizationLCM of 21 and 56 can be obtained by multiplying prime factors raised to their respective highest power, i.e. 23 × 31 × 71 = 168. Hence, the LCM of 21 and 56 by prime factorization is 168.
54 and 72= LCM of 54 and 72 by Prime Factorization
LCM of 54 and 72 by Prime FactorizationLCM of 54 and 72 can be obtained by multiplying prime factors raised to their respective highest power, i.e. 23 × 33 = 216. Hence, the LCM of 54 and 72 by prime factorization is 216.

Answer:
the first time I was so happy to be in the same way I wasted a few hours on my phone while my dad told my mom and dad that the only reason he didn't want you would do this year for the rest and if they were going through it and you would like him and he said it would have a lot more of you in that situation if I were you in a hurry up and then I was going through it and then you said that you didn't have my own insurance policy and that was a bad case to have the money back up for the last year or two to be sure win it and not have to be the one who can be in your home state or on your name as you
