GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(663, 649) = 430287
GCD(663, 649) = ( 663 x 649 ) / 430287
= 663 / 649
= 663
Step2:
LCM(1, 377) = 377
GCD(1, 377) = ( 1 x 377 ) / 377
= 1 / 377
= 1
Step3:
LCM(1, 432) = 432
GCD(1, 432) = ( 1 x 432 ) / 432
= 1 / 432
= 1
So, Greatest Common Divisor of 663, 649, 377, 432 is 1
