Given numbers are 402, 630, 171, 452

The list of prime factors of all numbers are

Prime factors of 402 are 2 x 3 x 67

Prime factors of 630 are 2 x 3 x 3 x 5 x 7

Prime factors of 171 are 3 x 3 x 19

Prime factors of 452 are 2 x 2 x 113

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

Given numbers are 402, 630, 171, 452

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

Apply this formula for all numbers.

Step1:

LCM(402, 630) = 42210

GCD(402, 630) = ( 402 x 630 ) / 42210

= 402 / 630

= 402

Step2:

LCM(6, 171) = 342

GCD(6, 171) = ( 6 x 171 ) / 342

= 6 / 171

= 6

Step3:

LCM(3, 452) = 1356

GCD(3, 452) = ( 3 x 452 ) / 1356

= 3 / 452

= 3

So, Greatest Common Divisor of 402, 630, 171, 452 is 1
