Given numbers are 133, 261, 744, 406

The list of prime factors of all numbers are

Prime factors of 133 are 7 x 19

Prime factors of 261 are 3 x 3 x 29

Prime factors of 744 are 2 x 2 x 2 x 3 x 31

Prime factors of 406 are 2 x 7 x 29

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 133, 261, 744, 406

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

Apply this formula for all numbers.

Step1:

LCM(133, 261) = 34713

GCD(133, 261) = ( 133 x 261 ) / 34713

= 133 / 261

= 133

Step2:

LCM(1, 744) = 744

GCD(1, 744) = ( 1 x 744 ) / 744

= 1 / 744

= 1

Step3:

LCM(1, 406) = 406

GCD(1, 406) = ( 1 x 406 ) / 406

= 1 / 406

= 1

So, Greatest Common Divisor of 133, 261, 744, 406 is 1
