Given numbers are 461, 108, 665, 688

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

Apply this formula for all numbers.

Step1:

LCM(461, 108) = 49788

GCD(461, 108) = ( 461 x 108 ) / 49788

= 461 / 108

= 461

Step2:

LCM(1, 665) = 665

GCD(1, 665) = ( 1 x 665 ) / 665

= 1 / 665

= 1

Step3:

LCM(1, 688) = 688

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

= 1 / 688

= 1

So, Greatest Common Divisor of 461, 108, 665, 688 is 1
