Given numbers are 290, 155, 371, 720

The list of prime factors of all numbers are

Prime factors of 290 are 2 x 5 x 29

Prime factors of 155 are 5 x 31

Prime factors of 371 are 7 x 53

Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5

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

Given numbers are 290, 155, 371, 720

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

Apply this formula for all numbers.

Step1:

LCM(290, 155) = 8990

GCD(290, 155) = ( 290 x 155 ) / 8990

= 290 / 155

= 290

Step2:

LCM(5, 371) = 1855

GCD(5, 371) = ( 5 x 371 ) / 1855

= 5 / 371

= 5

Step3:

LCM(1, 720) = 720

GCD(1, 720) = ( 1 x 720 ) / 720

= 1 / 720

= 1

So, Greatest Common Divisor of 290, 155, 371, 720 is 1
