Given numbers are 715, 406, 69, 310

The list of prime factors of all numbers are

Prime factors of 715 are 5 x 11 x 13

Prime factors of 406 are 2 x 7 x 29

Prime factors of 69 are 3 x 23

Prime factors of 310 are 2 x 5 x 31

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

Given numbers are 715, 406, 69, 310

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

Apply this formula for all numbers.

Step1:

LCM(715, 406) = 290290

GCD(715, 406) = ( 715 x 406 ) / 290290

= 715 / 406

= 715

Step2:

LCM(1, 69) = 69

GCD(1, 69) = ( 1 x 69 ) / 69

= 1 / 69

= 1

Step3:

LCM(1, 310) = 310

GCD(1, 310) = ( 1 x 310 ) / 310

= 1 / 310

= 1

So, Greatest Common Divisor of 715, 406, 69, 310 is 1
