The first step is to break each number into its prime factorization, then discern all the factors the two numbers have in common. Multiply these together. The result is the greatest common divisor.
What do u mean by greatest common divisor?
: the largest integer or the polynomial of highest degree that is an exact divisor of each of two or more integers or polynomials. — called also greatest common factor.
How do you find greatest common divisor?
Greatest common divisors can be computed by determining the prime factorizations of the two numbers and comparing factors. For example, to compute gcd(48, 180), we find the prime factorizations 48 = 24 · 31 and 180 = 22 · 32 · 51; the GCD is then 2 · 3 · 5 = 22 · 31 · 50 = 12, as shown in the Venn diagram.
How do you find the greatest common divisor by the step approach?
Divide the larger number into the smaller number. Divide the numerator into the denominator is the first task in using the step approach to finding the greatest common divisor. Divide the numerator into the denominator is the first task in using the step approach to finding the greatest common divisor.

Which is the greatest divisor of 15 and 10?
For example, the greatest common factor of 15 and 10 is 5, since both the numbers can be divided by 5. If a and b are two numbers then the greatest common divisor of both the numbers is denoted by gcd (a, b).
