Given numbers are 643, 429, 444, 450
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(643, 429) = 275847
GCD(643, 429) = ( 643 x 429 ) / 275847
= 643 / 429
= 643
Step2:
LCM(1, 444) = 444
GCD(1, 444) = ( 1 x 444 ) / 444
= 1 / 444
= 1
Step3:
LCM(1, 450) = 450
GCD(1, 450) = ( 1 x 450 ) / 450
= 1 / 450
= 1
So, Greatest Common Divisor of 643, 429, 444, 450 is 1
