GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(661, 287) = 189707
GCD(661, 287) = ( 661 x 287 ) / 189707
= 661 / 287
= 661
Step2:
LCM(1, 628) = 628
GCD(1, 628) = ( 1 x 628 ) / 628
= 1 / 628
= 1
Step3:
LCM(1, 499) = 499
GCD(1, 499) = ( 1 x 499 ) / 499
= 1 / 499
= 1
So, Greatest Common Divisor of 661, 287, 628, 499 is 1
