Given numbers are 782, 231, 781, 637

The list of prime factors of all numbers are

Prime factors of 782 are 2 x 17 x 23

Prime factors of 231 are 3 x 7 x 11

Prime factors of 781 are 11 x 71

Prime factors of 637 are 7 x 7 x 13

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

Given numbers are 782, 231, 781, 637

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

Apply this formula for all numbers.

Step1:

LCM(782, 231) = 180642

GCD(782, 231) = ( 782 x 231 ) / 180642

= 782 / 231

= 782

Step2:

LCM(1, 781) = 781

GCD(1, 781) = ( 1 x 781 ) / 781

= 1 / 781

= 1

Step3:

LCM(1, 637) = 637

GCD(1, 637) = ( 1 x 637 ) / 637

= 1 / 637

= 1

So, Greatest Common Divisor of 782, 231, 781, 637 is 1
