GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(744, 148) = 27528
GCD(744, 148) = ( 744 x 148 ) / 27528
= 744 / 148
= 744
Step2:
LCM(4, 649) = 2596
GCD(4, 649) = ( 4 x 649 ) / 2596
= 4 / 649
= 4
Step3:
LCM(1, 392) = 392
GCD(1, 392) = ( 1 x 392 ) / 392
= 1 / 392
= 1
So, Greatest Common Divisor of 744, 148, 649, 392 is 1
