Given numbers are 422, 270, 115, 661

The list of prime factors of all numbers are

Prime factors of 422 are 2 x 211

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

Prime factors of 115 are 5 x 23

Prime factors of 661 are 661

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

Given numbers are 422, 270, 115, 661

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

Apply this formula for all numbers.

Step1:

LCM(422, 270) = 56970

GCD(422, 270) = ( 422 x 270 ) / 56970

= 422 / 270

= 422

Step2:

LCM(2, 115) = 230

GCD(2, 115) = ( 2 x 115 ) / 230

= 2 / 115

= 2

Step3:

LCM(1, 661) = 661

GCD(1, 661) = ( 1 x 661 ) / 661

= 1 / 661

= 1

So, Greatest Common Divisor of 422, 270, 115, 661 is 1
