GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(197, 241) = 47477
GCD(197, 241) = ( 197 x 241 ) / 47477
= 197 / 241
= 197
Step2:
LCM(1, 495) = 495
GCD(1, 495) = ( 1 x 495 ) / 495
= 1 / 495
= 1
Step3:
LCM(1, 640) = 640
GCD(1, 640) = ( 1 x 640 ) / 640
= 1 / 640
= 1
So, Greatest Common Divisor of 197, 241, 495, 640 is 1
