Factors of 20:1,2,4,5,10,20Factors of 65:1,5,13,65The common factors are 1 and 5.
Common factors of 20 are; 1,2,4,5, and 20. 1x20=20, 2x10=20, 4x5=20, 5x4=20, 20x1+=20. If you have to show your work then just check mine.The factors of 20 are 1,2,4,5,10 and 20. For them to be common, they have to be compared to another set of factors.
You are 12-20. The only common factor of 11 and 21 is 1.
The only common factor is: 1
The common factors of 20 and 50 are: 1, 2, 5, 10.
1,11,12,13,14,15,16,17,18,19,2,6,7,8,9,3,4,5, those r some of the factors between 10 and 20
The GCF of 9 and 20 is 1. One way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 9 are 1, 3, and 9. The factors of 20 are 1, 2, 4, 5, 10, and 20. 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 9 are 3 and 3. The prime factors of 20 are 2, 2, and 5. There are no prime factors in common, so the numbers are relatively prime, which means the greatest common factor is 1. Another way to approach this is to look at the difference between 9 and 20, 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. Since 11 is a prime number, the greatest common factor must be either 1 or 11. The numbers 9 and 20 are not divisible by 11, so the greatest common factor must be 1.
1 and 5.
One way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 20 are 1, 2, 4, 5, 10, and 20. The factors of 55 are 1, 5, 11, and 55. 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 20 are 2, 2, and 5. The prime factors of 55 are 5 and 11. The prime factors in common are a single 5, so the greatest common factor is 5.
The factors of 50 are: 1, 2, 5, 10, 25, 50 None of them is between 11 and 20.
The GCF is 10.
1, 2 and 4
well. 1 11 1 2 4 5 10 20 so the GCF is 1
The GCF of 20, 55, and 85 is 5 One way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 20 are 1, 2, 4, 5, 10, and 20. The factors of 55 are 1, 5, 11, and 55. The factors of 85 are 1, 5, 17, and 85. 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 20 are 2, 2, and 5. The prime factors of 55 are 5 and 11. The prime factors of 85 are 5 and 17. The prime factors in common are a single 5, so the greatest common factor is 5.
Factors of 20:1,2,4,5,10,20Factors of 65:1,5,13,65The common factors are 1 and 5.
