Given numbers are 663, 649, 477, 632
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, 477) = 477
GCD(1, 477) = ( 1 x 477 ) / 477
= 1 / 477
= 1
Step3:
LCM(1, 632) = 632
GCD(1, 632) = ( 1 x 632 ) / 632
= 1 / 632
= 1
So, Greatest Common Divisor of 663, 649, 477, 632 is 1
