Given numbers are 680, 127, 665

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

Apply this formula for all numbers.

Step1:

LCM(680, 127) = 86360

GCD(680, 127) = ( 680 x 127 ) / 86360

= 680 / 127

= 680

Step2:

LCM(1, 665) = 665

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

= 1 / 665

= 1

So, Greatest Common Divisor of 680, 127, 665 is 1
