What is the greatest common factor of 87 and 29?
One way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 29 are 1 and 29.The factors of 87 are 1, 3, 29, and 87.The common factors are 1 and 29. Therefore, the greatest common factor is 29.The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factor of 29 is 29.The prime factors of 87 are 3 and 29.The prime factors in common are a single 29, so the greatest common factor is 29. == == 29 is a prime number so its only factors are 1 and 29. The factors of 87 are 1, 3, 29, and 87. The GCF of 29 and 87 is 29.The GCF is 29.

How do you use a factor tree to find the greatest common factor of 87 and 29?
It's not necessary for two reasons. First, 29 is a factor of 87 so it will automatically be the GCF of this problem. Second, since factor trees are designed to find prime numbers and 29 is already prime, it doesn't have a tree. But if you insist... 87 3,29 Here we have a factor tree, more like a factor shrub, that shows that the prime factors of 87 are 3 and 29. Since 29 is a factor of 29, the GCF is 29.
What are the prime factors of 20 not true for 50?
4 is a prime factor of 20 whereas it isn't a factor of 50.
How do you do a factor tree for 87?
87 3,29 Not much of a tree. More like a factor shrub.
When is the greatest common factor of two numbers is one of the numbers?
The greatest common factors (GCF) of two numbers is one of the numbers when the larger number is a multiple of the smaller number. Examples: The GCF of 10 and 20 is 10 (2 x 10 = 20) The GCF of 29 and 87 is 29 (3 x 29 = 87)
What is the prime factor of 87 using exponential notation?
31 x 291
Can you show me the factor tree of 87?
29x3 both prime so your done
What is the largest prime number of 20?
