Given numbers are 277, 646, 446, 129
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(277, 646) = 178942
GCD(277, 646) = ( 277 x 646 ) / 178942
= 277 / 646
= 277
Step2:
LCM(1, 446) = 446
GCD(1, 446) = ( 1 x 446 ) / 446
= 1 / 446
= 1
Step3:
LCM(1, 129) = 129
GCD(1, 129) = ( 1 x 129 ) / 129
= 1 / 129
= 1
So, Greatest Common Divisor of 277, 646, 446, 129 is 1
