Given numbers are 987, 963, 780, 860

The list of prime factors of all numbers are

Prime factors of 987 are 3 x 7 x 47

Prime factors of 963 are 3 x 3 x 107

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 860 are 2 x 2 x 5 x 43

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 987, 963, 780, 860

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(987, 963) = 316827

GCD(987, 963) = ( 987 x 963 ) / 316827

= 987 / 963

= 987

Step2:

LCM(3, 780) = 780

GCD(3, 780) = ( 3 x 780 ) / 780

= 3 / 780

= 3

Step3:

LCM(3, 860) = 2580

GCD(3, 860) = ( 3 x 860 ) / 2580

= 3 / 860

= 3

So, Greatest Common Divisor of 987, 963, 780, 860 is 1
