The prime factors of 20 are 2 and 5. The prime factors of 77 are 7 and 11. 20 times 77 is 1540 which has, as you might expect, the prime factors 2, 5 , 7 and 11, but is not prime.

What is the greatest common factor of 15 and 77?

The GCF of 15 and 77 is 1. The factors of 15 are 1, 3, 5, and 15. The factors of 77 are 1, 7, 11, and 77. The common factors are 1. Therefore the greatest common factor is 1, which means the two numbers are relatively prime. The greatest common factor can also be determined by prime factors. The prime factors of 15 are 3 and 5. The prime factors of 77 are 7 and 11. There are no common prime factors, so the two numbers are relatively prime, which means their only common factor is 1.

What is the factor tree of 77?

A factor tree breaks a number down into it's prime numbers.A prime number is a number that can only be divided by 1 and itself.For example: 3 is a prime number, because the only numbers that can be divided evenly into 3 are 1 and 3.Your number is 77. I can tell by looking at the number that it is divisible by 7 (note the double 7's in 77)77 / 7 = 11.This means that 7 * 11 = 77Your factor tree would look like:......77....../ \.....7*11Now we see if 7 and 11 can be broken down into smaller prime factors.Fortunately for us, 7 is already a prime number.And, as luck would have it, 11 is also a prime number.This completes the factor tree of 77.


Is 77 a prime number or a composite number?

7 is a factor of 77 so it cannot be a prime. So it has to be composite.It is composite since 7 x 11 is 77 and those are both primes. That is to say, it is the product of two primes and that makes it composite.


What is the greatest common factor of 35 and 77?

The GCF of 35 and 77 is 7One way to determine the greatest common factor is to find all the factors of the numbers and compare them.The factors of 35 are 1, 5, 7, and 35.The factors of 77 are 1, 7, 11, and 77.The common factors are 1 and 7. Therefore, the greatest common factor is 7.The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together.The prime factors of 35 are 5 and 7.The prime factors of 77 are 7 and 11.The prime factors in common are a single 7, so the greatest common factor is 7.

What is the greatest common factor for 22 and 77?

Look at the prime factorisation of both numbers: 22 = 2 * 11 77 = 7 * 11 There is only one common factor and that is 11.


What is the greatest common factor of 77?

There is not a greatest common factor of a single number, such as 77, because there cannot be a greatest 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 77 are 1, 7, 11, and 77. The prime factors of 77 are 7 and 11. Examples: The greatest common factor of 63 and 77 is 7. The greatest common factor of 74 and 77 is 1. The greatest common factor of 77 and 121 is 11.
