Given numbers are 253, 638, 433, 129
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(253, 638) = 14674
GCD(253, 638) = ( 253 x 638 ) / 14674
= 253 / 638
= 253
Step2:
LCM(11, 433) = 4763
GCD(11, 433) = ( 11 x 433 ) / 4763
= 11 / 433
= 11
Step3:
LCM(1, 129) = 129
GCD(1, 129) = ( 1 x 129 ) / 129
= 1 / 129
= 1
So, Greatest Common Divisor of 253, 638, 433, 129 is 1
