Given numbers are 987, 646, 980, 476

The list of prime factors of all numbers are

Prime factors of 987 are 3 x 7 x 47

Prime factors of 646 are 2 x 17 x 19

Prime factors of 980 are 2 x 2 x 5 x 7 x 7

Prime factors of 476 are 2 x 2 x 7 x 17

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

Given numbers are 987, 646, 980, 476

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

Apply this formula for all numbers.

Step1:

LCM(987, 646) = 637602

GCD(987, 646) = ( 987 x 646 ) / 637602

= 987 / 646

= 987

Step2:

LCM(1, 980) = 980

GCD(1, 980) = ( 1 x 980 ) / 980

= 1 / 980

= 1

Step3:

LCM(1, 476) = 476

GCD(1, 476) = ( 1 x 476 ) / 476

= 1 / 476

= 1

So, Greatest Common Divisor of 987, 646, 980, 476 is 1
