Given numbers are 600, 909, 450, 645
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(600, 909) = 181800
GCD(600, 909) = ( 600 x 909 ) / 181800
= 600 / 909
= 600
Step2:
LCM(3, 450) = 450
GCD(3, 450) = ( 3 x 450 ) / 450
= 3 / 450
= 3
Step3:
LCM(3, 645) = 645
GCD(3, 645) = ( 3 x 645 ) / 645
= 3 / 645
= 3
So, Greatest Common Divisor of 600, 909, 450, 645 is 3
