GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(392, 122) = 23912
GCD(392, 122) = ( 392 x 122 ) / 23912
= 392 / 122
= 392
Step2:
LCM(2, 124) = 124
GCD(2, 124) = ( 2 x 124 ) / 124
= 2 / 124
= 2
Step3:
LCM(2, 408) = 408
GCD(2, 408) = ( 2 x 408 ) / 408
= 2 / 408
= 2
So, Greatest Common Divisor of 392, 122, 124, 408 is 2
