Given numbers are 870, 129, 419, 306

The list of prime factors of all numbers are

Prime factors of 870 are 2 x 3 x 5 x 29

Prime factors of 129 are 3 x 43

Prime factors of 419 are 419

Prime factors of 306 are 2 x 3 x 3 x 17

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

Given numbers are 870, 129, 419, 306

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

Apply this formula for all numbers.

Step1:

LCM(870, 129) = 37410

GCD(870, 129) = ( 870 x 129 ) / 37410

= 870 / 129

= 870

Step2:

LCM(3, 419) = 1257

GCD(3, 419) = ( 3 x 419 ) / 1257

= 3 / 419

= 3

Step3:

LCM(1, 306) = 306

GCD(1, 306) = ( 1 x 306 ) / 306

= 1 / 306

= 1

So, Greatest Common Divisor of 870, 129, 419, 306 is 1
