Given numbers are 390, 231, 700, 790

The list of prime factors of all numbers are

Prime factors of 390 are 2 x 3 x 5 x 13

Prime factors of 231 are 3 x 7 x 11

Prime factors of 700 are 2 x 2 x 5 x 5 x 7

Prime factors of 790 are 2 x 5 x 79

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

Given numbers are 390, 231, 700, 790

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

Apply this formula for all numbers.

Step1:

LCM(390, 231) = 30030

GCD(390, 231) = ( 390 x 231 ) / 30030

= 390 / 231

= 390

Step2:

LCM(3, 700) = 2100

GCD(3, 700) = ( 3 x 700 ) / 2100

= 3 / 700

= 3

Step3:

LCM(1, 790) = 790

GCD(1, 790) = ( 1 x 790 ) / 790

= 1 / 790

= 1

So, Greatest Common Divisor of 390, 231, 700, 790 is 1
