Given numbers are 129, 865, 144, 919

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(129, 865) = 111585

GCD(129, 865) = ( 129 x 865 ) / 111585

= 129 / 865

= 129

Step2:

LCM(1, 144) = 144

GCD(1, 144) = ( 1 x 144 ) / 144

= 1 / 144

= 1

Step3:

LCM(1, 919) = 919

GCD(1, 919) = ( 1 x 919 ) / 919

= 1 / 919

= 1

So, Greatest Common Divisor of 129, 865, 144, 919 is 1
