Given numbers are 402, 455, 358, 115

The list of prime factors of all numbers are

Prime factors of 402 are 2 x 3 x 67

Prime factors of 455 are 5 x 7 x 13

Prime factors of 358 are 2 x 179

Prime factors of 115 are 5 x 23

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

Given numbers are 402, 455, 358, 115

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

Apply this formula for all numbers.

Step1:

LCM(402, 455) = 182910

GCD(402, 455) = ( 402 x 455 ) / 182910

= 402 / 455

= 402

Step2:

LCM(1, 358) = 358

GCD(1, 358) = ( 1 x 358 ) / 358

= 1 / 358

= 1

Step3:

LCM(1, 115) = 115

GCD(1, 115) = ( 1 x 115 ) / 115

= 1 / 115

= 1

So, Greatest Common Divisor of 402, 455, 358, 115 is 1
