Given numbers are 983, 736, 638, 840

The list of prime factors of all numbers are

Prime factors of 983 are 983

Prime factors of 736 are 2 x 2 x 2 x 2 x 2 x 23

Prime factors of 638 are 2 x 11 x 29

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

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

Given numbers are 983, 736, 638, 840

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

Apply this formula for all numbers.

Step1:

LCM(983, 736) = 723488

GCD(983, 736) = ( 983 x 736 ) / 723488

= 983 / 736

= 983

Step2:

LCM(1, 638) = 638

GCD(1, 638) = ( 1 x 638 ) / 638

= 1 / 638

= 1

Step3:

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

= 1 / 840

= 1

So, Greatest Common Divisor of 983, 736, 638, 840 is 1
