Given numbers are 985, 660, 631, 838

The list of prime factors of all numbers are

Prime factors of 985 are 5 x 197

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

Prime factors of 631 are 631

Prime factors of 838 are 2 x 419

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

Given numbers are 985, 660, 631, 838

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

Apply this formula for all numbers.

Step1:

LCM(985, 660) = 130020

GCD(985, 660) = ( 985 x 660 ) / 130020

= 985 / 660

= 985

Step2:

LCM(5, 631) = 3155

GCD(5, 631) = ( 5 x 631 ) / 3155

= 5 / 631

= 5

Step3:

LCM(1, 838) = 838

GCD(1, 838) = ( 1 x 838 ) / 838

= 1 / 838

= 1

So, Greatest Common Divisor of 985, 660, 631, 838 is 1
