Given numbers are 429, 374, 553, 129
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(429, 374) = 14586
GCD(429, 374) = ( 429 x 374 ) / 14586
= 429 / 374
= 429
Step2:
LCM(11, 553) = 6083
GCD(11, 553) = ( 11 x 553 ) / 6083
= 11 / 553
= 11
Step3:
LCM(1, 129) = 129
GCD(1, 129) = ( 1 x 129 ) / 129
= 1 / 129
= 1
So, Greatest Common Divisor of 429, 374, 553, 129 is 1
