What is the common factor of 16 and 20?
The factors of 16 are 1, 2, 4, 8, and 16. The factors of 20 are 1, 2, 4, 5, 10, and 20. The largest of the factors they have in common is 4, so 4 is the greatest common factor. Using prime factorization: The prime factors of 16 are 2, 2, 2, and 2. The prime factors of 20 are 2, 2, and 5. The prime factors in common are 2 and 2, so the greatest common factor is 2 x 2 = 4.
What are the common factors of 15and20 what is the greatest common factor gcf of 16and 20?
15 and 20: 10, 5, 1 16 and 20: 4
What is the greatest common factor of 16 and 80?
I know that 16 x 5 = 80, so the greatest common factor of 16 and 80 must be 16, since the greatest common factor cannot be larger than the small number. But, if you did not know this, you would need to compare their factors. The factors of 16 are 1, 2, 4, 8, and 16. The factors of 80 are 1, 2, 4, 5, 8, 10, 16, 20, 40, and 80. The largest of the factors they have in common is 16, so 16 is the greatest common factor. Or, you can determine the greatest common factor by their prime factors. The prime factors of 16 are 2, 2, 2, and 2. The prime factors of 80 are 2, 2, 2, 2, and 5. The prime factors they have in common are four 2s, so 2 x 2 x 2 x 2 = 16 is the greatest common factor.
What is the greatest common factor and factors of 16 and 40?
The factors of 16 are:1, 2, 4, 8, 16The factors of 40 are:1, 2, 4, 5, 8, 10, 20, 40The common factors are:1, 2, 4, 8The Greatest Common Factor:GCF = 8
What is the greatest common factor of 20 and 90?
The Greatest Common Factor of 20 and 90 is 10, because the factors of 20 are: 20:1,2,4,5,10,20 The factors of 90 are: 90:1,2,3,5,6,9,10,15,18,30,45,90 So, the common factors are 1,2,5,10 10 is the greatest number of them so 10 is the Greatest Common Factor. THE ANSWER IS 10
What are the greatest common factors of 17 and 20?
The factors of 17 are: 1, 17 The factors of 20 are: 1, 2, 4, 5, 10, 20 The common factors are: 1 The Greatest Common Factor: 1
What are the common factors and greatest common factor of 10 and 20?
1,2,5,10 are the common factors, and the Greatest Common Factor is 10.
What are the common factors and greatest common factor of 20?
There is neither a greatest common factor nor common factors of a single number, such as 20, because there cannot be any form of common factor without two or more numbers to compare. Common factors are factors that the numbers being compared have in common. The greatest common factor is the largest factor that all the numbers being compared have in common. Thus, since there are not two or more numbers to compare, there are neither common factors nor a greatest common factor. The factors of 20 are 1, 2, 4, 5, 10, and 20. The prime factors of 20 are 2, 2, and 5. Examples: The common factors of 20 and 70 are 1, 2, 5, and 10; the greatest common factor is 10. The common factors of 20 and 32 are 1, 2, and 4; the greatest common factor is 4. The common factors of 20 and 140 are 1, 2, 4, 5, 10, and 20; the greatest common factor is 20.
What are the greatest common factors of 20 and 36?
The Greatest Common Factor (GCF) of 20 and 36 is: 4
