Given numbers are 640, 307, 742
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(640, 307) = 196480
GCD(640, 307) = ( 640 x 307 ) / 196480
= 640 / 307
= 640
Step2:
LCM(1, 742) = 742
GCD(1, 742) = ( 1 x 742 ) / 742
= 1 / 742
= 1
So, Greatest Common Divisor of 640, 307, 742 is 1
