Given numbers are 290, 862, 639, 504

The list of prime factors of all numbers are

Prime factors of 290 are 2 x 5 x 29

Prime factors of 862 are 2 x 431

Prime factors of 639 are 3 x 3 x 71

Prime factors of 504 are 2 x 2 x 2 x 3 x 3 x 7

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

Given numbers are 290, 862, 639, 504

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

Apply this formula for all numbers.

Step1:

LCM(290, 862) = 124990

GCD(290, 862) = ( 290 x 862 ) / 124990

= 290 / 862

= 290

Step2:

LCM(2, 639) = 1278

GCD(2, 639) = ( 2 x 639 ) / 1278

= 2 / 639

= 2

Step3:

LCM(1, 504) = 504

GCD(1, 504) = ( 1 x 504 ) / 504

= 1 / 504

= 1

So, Greatest Common Divisor of 290, 862, 639, 504 is 1
