GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(649, 425) = 275825
GCD(649, 425) = ( 649 x 425 ) / 275825
= 649 / 425
= 649
Step2:
LCM(1, 393) = 393
GCD(1, 393) = ( 1 x 393 ) / 393
= 1 / 393
= 1
Step3:
LCM(1, 227) = 227
GCD(1, 227) = ( 1 x 227 ) / 227
= 1 / 227
= 1
So, Greatest Common Divisor of 649, 425, 393, 227 is 1
