Given numbers are 396, 121, 288, 656
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(396, 121) = 4356
GCD(396, 121) = ( 396 x 121 ) / 4356
= 396 / 121
= 396
Step2:
LCM(11, 288) = 3168
GCD(11, 288) = ( 11 x 288 ) / 3168
= 11 / 288
= 11
Step3:
LCM(1, 656) = 656
GCD(1, 656) = ( 1 x 656 ) / 656
= 1 / 656
= 1
So, Greatest Common Divisor of 396, 121, 288, 656 is 1
