GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(495, 123) = 20295
GCD(495, 123) = ( 495 x 123 ) / 20295
= 495 / 123
= 495
Step2:
LCM(3, 870) = 870
GCD(3, 870) = ( 3 x 870 ) / 870
= 3 / 870
= 3
Step3:
LCM(3, 609) = 609
GCD(3, 609) = ( 3 x 609 ) / 609
= 3 / 609
= 3
So, Greatest Common Divisor of 495, 123, 870, 609 is 3
