Given numbers are 781, 640, 609, 262

The list of prime factors of all numbers are

Prime factors of 781 are 11 x 71

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 609 are 3 x 7 x 29

Prime factors of 262 are 2 x 131

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

Given numbers are 781, 640, 609, 262

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

Apply this formula for all numbers.

Step1:

LCM(781, 640) = 499840

GCD(781, 640) = ( 781 x 640 ) / 499840

= 781 / 640

= 781

Step2:

LCM(1, 609) = 609

GCD(1, 609) = ( 1 x 609 ) / 609

= 1 / 609

= 1

Step3:

LCM(1, 262) = 262

GCD(1, 262) = ( 1 x 262 ) / 262

= 1 / 262

= 1

So, Greatest Common Divisor of 781, 640, 609, 262 is 1
