Given numbers are 450, 407, 129
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(450, 407) = 183150
GCD(450, 407) = ( 450 x 407 ) / 183150
= 450 / 407
= 450
Step2:
LCM(1, 129) = 129
GCD(1, 129) = ( 1 x 129 ) / 129
= 1 / 129
= 1
So, Greatest Common Divisor of 450, 407, 129 is 1
