What is the greatest common factor of 180 and 240?
The greatest common factor (GCF) is also known as greatest common divisor (GCD).
First we have to find the prime factorization of 180
180 = 2² × 3² × 5
Then we have to find the prime factorization of 240
240 = 2⁴ × 3 × 5
Now we have to multiply the common factors to both numbers with less exponent.
GCF = 2² × 3 × 5 = 60
Answer : GCF(180,240) = 60
Hope this helps!
