It's not. 5 is.
The GCF of 30 and 50 is 1
The GCF is 1.
A single number does not have a common factor. Common factors are factors that two or more numbers have in common. The greatest common factor of a pair of numbers over 50 could be any number, depending on the pair of numbers. The greatest common factor of 51 and 100 is 1. The greatest common factor of 51, 52, 53, 54, 55, and 56 is 1. The greatest common factor of 52 and 100 is 2. The greatest common factor of 57 and 102 is 3.
The greatest common factor of 30 and 39 is 3.
The greatest common factor of 3 and 63 is 3.
One way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 18 are 1, 2, 3, 6, 9, and 18. The factors of 50 are 1, 2, 5, 10, 25, and 50. The common factors are 1 and 2, so the greatest common factor is 2. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factors of 18 are 2, 3, and 3. The prime factors of 50 are 2, 5, and 5. The prime factors in common are a single 2, so the greatest common factor is 2.
The greatest common factor of 24 and 57 is 3.
12 = 2 * 2 * 3 50 = 2 * * 5 * 5 ---------------------------- The only common factor is 2. ---------------------------- GCF = 2
One way to approach this is to look at the difference between 45 and 50, which is 5. The greatest common factor of two numbers cannot be larger than the difference between the two numbers and must be a factor of the difference. Since both 45 and 50 are divisible by 5, the greatest common factor is 5. Another way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 45 are 1, 3, 5, 9, 15, and 45. The factors of 50 are 1, 2, 5, 10, 25, and 50. The common factors are 1 and 5. Therefore, the greatest common factor is 5. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factors of 45 are 3, 3, and 5. The prime factors of 50 are 2, 5, and 5. The prime factors in common are a single 5, so the greatest common factor is 5.
The greatest common factor of 3 and 57 is 3
The greatest common factor of 3 and 23 is 1
The Greatest Common Factor (GCF) is: 3
