GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(917, 287) = 37597
GCD(917, 287) = ( 917 x 287 ) / 37597
= 917 / 287
= 917
Step2:
LCM(7, 322) = 322
GCD(7, 322) = ( 7 x 322 ) / 322
= 7 / 322
= 7
Step3:
LCM(7, 640) = 4480
GCD(7, 640) = ( 7 x 640 ) / 4480
= 7 / 640
= 7
So, Greatest Common Divisor of 917, 287, 322, 640 is 1
