Given numbers are 640, 687, 274
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(640, 687) = 439680
GCD(640, 687) = ( 640 x 687 ) / 439680
= 640 / 687
= 640
Step2:
LCM(1, 274) = 274
GCD(1, 274) = ( 1 x 274 ) / 274
= 1 / 274
= 1
So, Greatest Common Divisor of 640, 687, 274 is 1
