GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(493, 918) = 26622
GCD(493, 918) = ( 493 x 918 ) / 26622
= 493 / 918
= 493
Step2:
LCM(17, 311) = 5287
GCD(17, 311) = ( 17 x 311 ) / 5287
= 17 / 311
= 17
Step3:
LCM(1, 645) = 645
GCD(1, 645) = ( 1 x 645 ) / 645
= 1 / 645
= 1
So, Greatest Common Divisor of 493, 918, 311, 645 is 1
