GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(640, 819) = 524160
GCD(640, 819) = ( 640 x 819 ) / 524160
= 640 / 819
= 640
Step2:
LCM(1, 922) = 922
GCD(1, 922) = ( 1 x 922 ) / 922
= 1 / 922
= 1
Step3:
LCM(1, 307) = 307
GCD(1, 307) = ( 1 x 307 ) / 307
= 1 / 307
= 1
So, Greatest Common Divisor of 640, 819, 922, 307 is 1
