Given numbers are 782, 453, 990, 634

The list of prime factors of all numbers are

Prime factors of 782 are 2 x 17 x 23

Prime factors of 453 are 3 x 151

Prime factors of 990 are 2 x 3 x 3 x 5 x 11

Prime factors of 634 are 2 x 317

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

Given numbers are 782, 453, 990, 634

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

Apply this formula for all numbers.

Step1:

LCM(782, 453) = 354246

GCD(782, 453) = ( 782 x 453 ) / 354246

= 782 / 453

= 782

Step2:

LCM(1, 990) = 990

GCD(1, 990) = ( 1 x 990 ) / 990

= 1 / 990

= 1

Step3:

LCM(1, 634) = 634

GCD(1, 634) = ( 1 x 634 ) / 634

= 1 / 634

= 1

So, Greatest Common Divisor of 782, 453, 990, 634 is 1
