Given numbers are 939, 470, 581, 640
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(939, 470) = 441330
GCD(939, 470) = ( 939 x 470 ) / 441330
= 939 / 470
= 939
Step2:
LCM(1, 581) = 581
GCD(1, 581) = ( 1 x 581 ) / 581
= 1 / 581
= 1
Step3:
LCM(1, 640) = 640
GCD(1, 640) = ( 1 x 640 ) / 640
= 1 / 640
= 1
So, Greatest Common Divisor of 939, 470, 581, 640 is 1
