GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(649, 123) = 79827
GCD(649, 123) = ( 649 x 123 ) / 79827
= 649 / 123
= 649
Step2:
LCM(1, 381) = 381
GCD(1, 381) = ( 1 x 381 ) / 381
= 1 / 381
= 1
Step3:
LCM(1, 629) = 629
GCD(1, 629) = ( 1 x 629 ) / 629
= 1 / 629
= 1
So, Greatest Common Divisor of 649, 123, 381, 629 is 1
