Given numbers are 987, 185, 707, 831

The list of prime factors of all numbers are

Prime factors of 987 are 3 x 7 x 47

Prime factors of 185 are 5 x 37

Prime factors of 707 are 7 x 101

Prime factors of 831 are 3 x 277

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

Given numbers are 987, 185, 707, 831

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

Apply this formula for all numbers.

Step1:

LCM(987, 185) = 182595

GCD(987, 185) = ( 987 x 185 ) / 182595

= 987 / 185

= 987

Step2:

LCM(1, 707) = 707

GCD(1, 707) = ( 1 x 707 ) / 707

= 1 / 707

= 1

Step3:

LCM(1, 831) = 831

GCD(1, 831) = ( 1 x 831 ) / 831

= 1 / 831

= 1

So, Greatest Common Divisor of 987, 185, 707, 831 is 1
