The list of prime factors of all numbers are

Prime factors of 658 are 2 x 7 x 47

Prime factors of 987 are 3 x 7 x 47

Prime factors of 404 are 2 x 2 x 101

Prime factors of 828 are 2 x 2 x 3 x 3 x 23

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

Given numbers are 658, 987, 404, 828

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

Apply this formula for all numbers.

Step1:

LCM(658, 987) = 1974

GCD(658, 987) = ( 658 x 987 ) / 1974

= 658 / 987

= 658

Step2:

LCM(329, 404) = 132916

GCD(329, 404) = ( 329 x 404 ) / 132916

= 329 / 404

= 329

Step3:

LCM(1, 828) = 828

GCD(1, 828) = ( 1 x 828 ) / 828

= 1 / 828

= 1

So, Greatest Common Divisor of 658, 987, 404, 828 is 1
