GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(297, 645) = 63855
GCD(297, 645) = ( 297 x 645 ) / 63855
= 297 / 645
= 297
Step2:
LCM(3, 242) = 726
GCD(3, 242) = ( 3 x 242 ) / 726
= 3 / 242
= 3
Step3:
LCM(1, 609) = 609
GCD(1, 609) = ( 1 x 609 ) / 609
= 1 / 609
= 1
So, Greatest Common Divisor of 297, 645, 242, 609 is 1
