Given numbers are 428, 252, 130, 261

The list of prime factors of all numbers are

Prime factors of 428 are 2 x 2 x 107

Prime factors of 252 are 2 x 2 x 3 x 3 x 7

Prime factors of 130 are 2 x 5 x 13

Prime factors of 261 are 3 x 3 x 29

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

Given numbers are 428, 252, 130, 261

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

Apply this formula for all numbers.

Step1:

LCM(428, 252) = 26964

GCD(428, 252) = ( 428 x 252 ) / 26964

= 428 / 252

= 428

Step2:

LCM(4, 130) = 260

GCD(4, 130) = ( 4 x 130 ) / 260

= 4 / 130

= 4

Step3:

LCM(2, 261) = 522

GCD(2, 261) = ( 2 x 261 ) / 522

= 2 / 261

= 2

So, Greatest Common Divisor of 428, 252, 130, 261 is 1
