What is the greatest common factor of 24 and 25?
24 and 25 have no common factor, other than one. There can be only one "greatest". There are two ways to solve for the greatest common factor. One way is to solve is to find the common prime factors and multiply them. So 24 = 2*2*2*3 and 25 = 5*5 Since they do not have common prime factors they do not have a GCF. Another way to solve it (just to reassure you) is to list the factors. 1. 24: 1, 2, 3, 4, 6, 8, 12, 24 25: 1, 5, 25 2. Again, you see they don't have a common factor. So technically the greatest common factor is 1.
What is the greatest common factor of 2 and 211?
The only factors of 2 are 1 and 2, so the greatest common factor is 2 if the other number is even or 1 if it is not. 211 is not even. Therefore, the greatest common factor is 1. Another way to solve this is by knowing that when both numbers are prime numbers, the greatest common factor is 1. Both 2 and 211 are prime numbers, so their greatest common factor is 1. One more way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 2 are 1 and 2. The factors of 211 are 1 and 211. The only common factor is 1. Therefore, the greatest common factor is 1, which means the numbers are relatively prime. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factor of 2 is 2. The prime factor of 211 is 211. There are no prime factors in common, so the numbers are relatively prime, which means the greatest common factor is 1.
How does factor pair solve the problem?
That depends on what the problem is.
What is the greatest common factor of 8 and 52?
The greatest common factor of 8 and 52 is 4The factors of 52 are 1, 2, 4, 13, 26, and 52.The factors of 8 are 1, 2, 4, and 8.The greatest common factor is 4.You can also solve it by looking at the prime factors.The prime factors of 52 are 2, 2, and 13.The prime factors of 8 are 2, 2, 2, and 2.The common factors are 2 and 2, so the greatest common factor is 2 x 2 = 4.
How do you solve the greatest common factor for 21 24 and 27?
List the factors. The factors of 21 are: 1, 3, 7, 21 The factors of 24 are: 1, 2, 3, 4, 6, 8, 12, 24 The factors of 27 are: 1, 3, 9, 27 The common factors are: 1, 3 The Greatest Common Factor: GCF = 3
