Given numbers are 144, 656, 171, 836
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(144, 656) = 5904
GCD(144, 656) = ( 144 x 656 ) / 5904
= 144 / 656
= 144
Step2:
LCM(16, 171) = 2736
GCD(16, 171) = ( 16 x 171 ) / 2736
= 16 / 171
= 16
Step3:
LCM(1, 836) = 836
GCD(1, 836) = ( 1 x 836 ) / 836
= 1 / 836
= 1
So, Greatest Common Divisor of 144, 656, 171, 836 is 1
