Given numbers are 658, 497, 102, 688

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

Apply this formula for all numbers.

Step1:

LCM(658, 497) = 46718

GCD(658, 497) = ( 658 x 497 ) / 46718

= 658 / 497

= 658

Step2:

LCM(7, 102) = 714

GCD(7, 102) = ( 7 x 102 ) / 714

= 7 / 102

= 7

Step3:

LCM(1, 688) = 688

GCD(1, 688) = ( 1 x 688 ) / 688

= 1 / 688

= 1

So, Greatest Common Divisor of 658, 497, 102, 688 is 1
