Given numbers are 270, 425, 780, 691

The list of prime factors of all numbers are

Prime factors of 270 are 2 x 3 x 3 x 3 x 5

Prime factors of 425 are 5 x 5 x 17

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 691 are 691

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

Given numbers are 270, 425, 780, 691

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

Apply this formula for all numbers.

Step1:

LCM(270, 425) = 22950

GCD(270, 425) = ( 270 x 425 ) / 22950

= 270 / 425

= 270

Step2:

LCM(5, 780) = 780

GCD(5, 780) = ( 5 x 780 ) / 780

= 5 / 780

= 5

Step3:

LCM(5, 691) = 3455

GCD(5, 691) = ( 5 x 691 ) / 3455

= 5 / 691

= 5

So, Greatest Common Divisor of 270, 425, 780, 691 is 1
