GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(399, 530) = 211470
GCD(399, 530) = ( 399 x 530 ) / 211470
= 399 / 530
= 399
Step2:
LCM(1, 386) = 386
GCD(1, 386) = ( 1 x 386 ) / 386
= 1 / 386
= 1
Step3:
LCM(1, 972) = 972
GCD(1, 972) = ( 1 x 972 ) / 972
= 1 / 972
= 1
So, Greatest Common Divisor of 399, 530, 386, 972 is 1
