What are the common factors of 5 and 21?
The only common factor of 5 and 21 is 1.
What is the greatest common factor of 20 21 and 25?
The greatest common factor of 20, 21, and 25 is 1. Although 20 and 25 can be divisible by 5, 21 can not. Therefore, the only common factor between these three numbers is 1 and it's the greatest one as well.
What is the greatest common factor of 10 and 21?
The GCF of 10 and 21 is 1. One way to approach this is to look at the difference between 10 and 21, which is 11. 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. The greatest common factor cannot be larger than the smallest number, so it cannot be 11. The only other factor of 11 is 1, so the greatest common factor is 1. Another way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 10 are 1, 2, 5, and 10. The factors of 21 are 1, 3, 7, and 21. 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 factors of 10 are 2 and 5. The prime factors of 21 are 3 and 7. There are no prime factors in common, so the numbers are relatively prime, which means the greatest common factor is 1.
What is the greatest common factor between 5 and 35?
5
What is the greatest common factor of 21 and 5 and 35?
GCF(21, 5, 35) = 1
What is the greatest common factor between 65 and 35?
The greatest common factor (GCF) is: 5
What is the greatest common factor between 645 and 1000?
The greatest common factor (GCF) is: 5
What is the greatest common factor between 2065 and 190?
The greatest common factor (GCF) is: 5
What is the least common factor of 5 and 21?
The least common factor of any two or more positive integers is always 1
What is the greatest common factor of 21 35?
21 = (3)(7)35 = (5)(7)7
What is the greatest common factor for 65 and 80?
The greatest common factor between 55 and 80 is 5.
What go into 21 and 35?
The numbers that go into both 21 and 35 are their common factors. The factors of 21 are 1, 3, 7, and 21, while the factors of 35 are 1, 5, 7, and 35. The only common factor between them is 7. Thus, 7 is the greatest common divisor of 21 and 35.
