GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(749, 457) = 342293
GCD(749, 457) = ( 749 x 457 ) / 342293
= 749 / 457
= 749
Step2:
LCM(1, 947) = 947
GCD(1, 947) = ( 1 x 947 ) / 947
= 1 / 947
= 1
Step3:
LCM(1, 394) = 394
GCD(1, 394) = ( 1 x 394 ) / 394
= 1 / 394
= 1
So, Greatest Common Divisor of 749, 457, 947, 394 is 1
