Given numbers are 144, 231, 40
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(144, 231) = 11088
GCD(144, 231) = ( 144 x 231 ) / 11088
= 144 / 231
= 144
Step2:
LCM(3, 40) = 120
GCD(3, 40) = ( 3 x 40 ) / 120
= 3 / 40
= 3
So, Greatest Common Divisor of 144, 231, 40 is 1
