Given numbers are 688, 136, 196, 495

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

Apply this formula for all numbers.

Step1:

LCM(688, 136) = 11696

GCD(688, 136) = ( 688 x 136 ) / 11696

= 688 / 136

= 688

Step2:

LCM(8, 196) = 392

GCD(8, 196) = ( 8 x 196 ) / 392

= 8 / 196

= 8

Step3:

LCM(4, 495) = 1980

GCD(4, 495) = ( 4 x 495 ) / 1980

= 4 / 495

= 4

So, Greatest Common Divisor of 688, 136, 196, 495 is 1
