Given numbers are 402, 305, 845, 506

The list of prime factors of all numbers are

Prime factors of 402 are 2 x 3 x 67

Prime factors of 305 are 5 x 61

Prime factors of 845 are 5 x 13 x 13

Prime factors of 506 are 2 x 11 x 23

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

Given numbers are 402, 305, 845, 506

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

Apply this formula for all numbers.

Step1:

LCM(402, 305) = 122610

GCD(402, 305) = ( 402 x 305 ) / 122610

= 402 / 305

= 402

Step2:

LCM(1, 845) = 845

GCD(1, 845) = ( 1 x 845 ) / 845

= 1 / 845

= 1

Step3:

LCM(1, 506) = 506

GCD(1, 506) = ( 1 x 506 ) / 506

= 1 / 506

= 1

So, Greatest Common Divisor of 402, 305, 845, 506 is 1
