Given numbers are 663, 351, 446, 655
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(663, 351) = 5967
GCD(663, 351) = ( 663 x 351 ) / 5967
= 663 / 351
= 663
Step2:
LCM(39, 446) = 17394
GCD(39, 446) = ( 39 x 446 ) / 17394
= 39 / 446
= 39
Step3:
LCM(1, 655) = 655
GCD(1, 655) = ( 1 x 655 ) / 655
= 1 / 655
= 1
So, Greatest Common Divisor of 663, 351, 446, 655 is 1
