GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(123, 648) = 26568
GCD(123, 648) = ( 123 x 648 ) / 26568
= 123 / 648
= 123
Step2:
LCM(3, 369) = 369
GCD(3, 369) = ( 3 x 369 ) / 369
= 3 / 369
= 3
Step3:
LCM(3, 255) = 255
GCD(3, 255) = ( 3 x 255 ) / 255
= 3 / 255
= 3
So, Greatest Common Divisor of 123, 648, 369, 255 is 3
