Given numbers are 129, 660, 956, 149

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

Apply this formula for all numbers.

Step1:

LCM(129, 660) = 28380

GCD(129, 660) = ( 129 x 660 ) / 28380

= 129 / 660

= 129

Step2:

LCM(3, 956) = 2868

GCD(3, 956) = ( 3 x 956 ) / 2868

= 3 / 956

= 3

Step3:

LCM(1, 149) = 149

GCD(1, 149) = ( 1 x 149 ) / 149

= 1 / 149

= 1

So, Greatest Common Divisor of 129, 660, 956, 149 is 1
