Given numbers are 645, 327, 242, 266
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(645, 327) = 70305
GCD(645, 327) = ( 645 x 327 ) / 70305
= 645 / 327
= 645
Step2:
LCM(3, 242) = 726
GCD(3, 242) = ( 3 x 242 ) / 726
= 3 / 242
= 3
Step3:
LCM(1, 266) = 266
GCD(1, 266) = ( 1 x 266 ) / 266
= 1 / 266
= 1
So, Greatest Common Divisor of 645, 327, 242, 266 is 1
