Given numbers are 637, 235, 451, 840

The list of prime factors of all numbers are

Prime factors of 637 are 7 x 7 x 13

Prime factors of 235 are 5 x 47

Prime factors of 451 are 11 x 41

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 637, 235, 451, 840

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

Apply this formula for all numbers.

Step1:

LCM(637, 235) = 149695

GCD(637, 235) = ( 637 x 235 ) / 149695

= 637 / 235

= 637

Step2:

LCM(1, 451) = 451

GCD(1, 451) = ( 1 x 451 ) / 451

= 1 / 451

= 1

Step3:

LCM(1, 840) = 840

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

= 1 / 840

= 1

So, Greatest Common Divisor of 637, 235, 451, 840 is 1
