Given numbers are 840, 665, 637

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

Apply this formula for all numbers.

Step1:

LCM(840, 665) = 15960

GCD(840, 665) = ( 840 x 665 ) / 15960

= 840 / 665

= 840

Step2:

LCM(35, 637) = 3185

GCD(35, 637) = ( 35 x 637 ) / 3185

= 35 / 637

= 35

So, Greatest Common Divisor of 840, 665, 637 is 7
