Given numbers are 642, 536, 779

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

Apply this formula for all numbers.

Step1:

LCM(642, 536) = 172056

GCD(642, 536) = ( 642 x 536 ) / 172056

= 642 / 536

= 642

Step2:

LCM(2, 779) = 1558

GCD(2, 779) = ( 2 x 779 ) / 1558

= 2 / 779

= 2

So, Greatest Common Divisor of 642, 536, 779 is 1
