Given numbers are 406, 261, 342, 860

The list of prime factors of all numbers are

Prime factors of 406 are 2 x 7 x 29

Prime factors of 261 are 3 x 3 x 29

Prime factors of 342 are 2 x 3 x 3 x 19

Prime factors of 860 are 2 x 2 x 5 x 43

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

Given numbers are 406, 261, 342, 860

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

Apply this formula for all numbers.

Step1:

LCM(406, 261) = 3654

GCD(406, 261) = ( 406 x 261 ) / 3654

= 406 / 261

= 406

Step2:

LCM(29, 342) = 9918

GCD(29, 342) = ( 29 x 342 ) / 9918

= 29 / 342

= 29

Step3:

LCM(1, 860) = 860

GCD(1, 860) = ( 1 x 860 ) / 860

= 1 / 860

= 1

So, Greatest Common Divisor of 406, 261, 342, 860 is 1
