Given numbers are 730, 515, 290, 687

The list of prime factors of all numbers are

Prime factors of 730 are 2 x 5 x 73

Prime factors of 515 are 5 x 103

Prime factors of 290 are 2 x 5 x 29

Prime factors of 687 are 3 x 229

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

Given numbers are 730, 515, 290, 687

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

Apply this formula for all numbers.

Step1:

LCM(730, 515) = 75190

GCD(730, 515) = ( 730 x 515 ) / 75190

= 730 / 515

= 730

Step2:

LCM(5, 290) = 290

GCD(5, 290) = ( 5 x 290 ) / 290

= 5 / 290

= 5

Step3:

LCM(5, 687) = 3435

GCD(5, 687) = ( 5 x 687 ) / 3435

= 5 / 687

= 5

So, Greatest Common Divisor of 730, 515, 290, 687 is 1
