Given numbers are 676, 136, 647

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

Apply this formula for all numbers.

Step1:

LCM(676, 136) = 22984

GCD(676, 136) = ( 676 x 136 ) / 22984

= 676 / 136

= 676

Step2:

LCM(4, 647) = 2588

GCD(4, 647) = ( 4 x 647 ) / 2588

= 4 / 647

= 4

So, Greatest Common Divisor of 676, 136, 647 is 1
