Given numbers are 781, 216, 138, 650

The list of prime factors of all numbers are

Prime factors of 781 are 11 x 71

Prime factors of 216 are 2 x 2 x 2 x 3 x 3 x 3

Prime factors of 138 are 2 x 3 x 23

Prime factors of 650 are 2 x 5 x 5 x 13

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

Given numbers are 781, 216, 138, 650

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

Apply this formula for all numbers.

Step1:

LCM(781, 216) = 168696

GCD(781, 216) = ( 781 x 216 ) / 168696

= 781 / 216

= 781

Step2:

LCM(1, 138) = 138

GCD(1, 138) = ( 1 x 138 ) / 138

= 1 / 138

= 1

Step3:

LCM(1, 650) = 650

GCD(1, 650) = ( 1 x 650 ) / 650

= 1 / 650

= 1

So, Greatest Common Divisor of 781, 216, 138, 650 is 1
