Given numbers are 144, 661, 373, 129

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

Apply this formula for all numbers.

Step1:

LCM(144, 661) = 95184

GCD(144, 661) = ( 144 x 661 ) / 95184

= 144 / 661

= 144

Step2:

LCM(1, 373) = 373

GCD(1, 373) = ( 1 x 373 ) / 373

= 1 / 373

= 1

Step3:

LCM(1, 129) = 129

GCD(1, 129) = ( 1 x 129 ) / 129

= 1 / 129

= 1

So, Greatest Common Divisor of 144, 661, 373, 129 is 1
