Given numbers are 688, 416, 117, 641

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

Apply this formula for all numbers.

Step1:

LCM(688, 416) = 17888

GCD(688, 416) = ( 688 x 416 ) / 17888

= 688 / 416

= 688

Step2:

LCM(16, 117) = 1872

GCD(16, 117) = ( 16 x 117 ) / 1872

= 16 / 117

= 16

Step3:

LCM(1, 641) = 641

GCD(1, 641) = ( 1 x 641 ) / 641

= 1 / 641

= 1

So, Greatest Common Divisor of 688, 416, 117, 641 is 1
