GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(656, 123) = 1968
GCD(656, 123) = ( 656 x 123 ) / 1968
= 656 / 123
= 656
Step2:
LCM(41, 388) = 15908
GCD(41, 388) = ( 41 x 388 ) / 15908
= 41 / 388
= 41
Step3:
LCM(1, 448) = 448
GCD(1, 448) = ( 1 x 448 ) / 448
= 1 / 448
= 1
So, Greatest Common Divisor of 656, 123, 388, 448 is 1
