What is the GCF of the 85?
You need at least two numbers to find a GCF.
What is the GCF of 616?
You need at least two numbers to find a GCF. If that's 16 and 66, the GCF is 2.
What is the GCF 240?
You need at least two numbers to find a GCF.
What is the GCF of 440?
You need at least two numbers to find a GCF.
How do you find a pair of numbers when the GCF is given?
To find a pair of numbers with a given GCF, take the GCF number and double it. The pair of numbers is the GCF, and two times the GCF. For instance, two numbers with a GCF of 3 are 3 and 6.
How do you find the gcf of 78?
You don't; you need at least two numbers to find a GCF.
What is the GCF of 156?
You need at least two numbers to find a GCF.
Hcf of two numbers is 87 and their LCM is 24960 if one of two numbers is 348 find the other number?
As a general rule, the product of the GCF and the LCM is equal to the product of the original numbers. That would make the answer to this problem 6240. Unfortunately, the GCF of 348 and 6240 isn't 87 and their LCM isn't 24960. Someone notated this problem incorrectly.
What is the GCF of numbers for 21?
You need at least two numbers to find a GCF. The GCF of 21 and 42 is 21.

What is the greatest common factor of 736?
You need at least two numbers to find a GCF. If that's 72 and 96, the GCF is 24.
How can you find the gcf of two numbers without knowing the factors?
If one of the numbers is a multiple of the other, the smaller number is the GCF. If the two numbers are prime numbers, the GCF is 1. If the numbers are consecutive, the GCF is 1. If the numbers are consecutive even numbers, the GCF is 2.
What is the GCF of the 85?
You need at least two numbers to find a GCF.
What is the GCF of 616?
You need at least two numbers to find a GCF. If that's 16 and 66, the GCF is 2.
