GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(392, 570) = 111720
GCD(392, 570) = ( 392 x 570 ) / 111720
= 392 / 570
= 392
Step2:
LCM(2, 387) = 774
GCD(2, 387) = ( 2 x 387 ) / 774
= 2 / 387
= 2
Step3:
LCM(1, 979) = 979
GCD(1, 979) = ( 1 x 979 ) / 979
= 1 / 979
= 1
So, Greatest Common Divisor of 392, 570, 387, 979 is 1
