Given numbers are 636, 812, 497, 781

The list of prime factors of all numbers are

Prime factors of 636 are 2 x 2 x 3 x 53

Prime factors of 812 are 2 x 2 x 7 x 29

Prime factors of 497 are 7 x 71

Prime factors of 781 are 11 x 71

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

Given numbers are 636, 812, 497, 781

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

Apply this formula for all numbers.

Step1:

LCM(636, 812) = 129108

GCD(636, 812) = ( 636 x 812 ) / 129108

= 636 / 812

= 636

Step2:

LCM(4, 497) = 1988

GCD(4, 497) = ( 4 x 497 ) / 1988

= 4 / 497

= 4

Step3:

LCM(1, 781) = 781

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

= 1 / 781

= 1

So, Greatest Common Divisor of 636, 812, 497, 781 is 1
