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.
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.
Can two numbers have the same greatest common factor?
Two numbers have a GCF. Two sets of two numbers may have the same GCF.
What is the GCF of 156?
You need at least two numbers to find a GCF.
Are 143 and 63 relatively prime?
You can calculate the gcf (greatest common factor) of the two numbers; one quick way to do this is using Euclid's algorithm.If the gcf of two numbers is 1, then the numbers are relatively prime.
