Given numbers are 478, 817, 402, 945

The list of prime factors of all numbers are

Prime factors of 478 are 2 x 239

Prime factors of 817 are 19 x 43

Prime factors of 402 are 2 x 3 x 67

Prime factors of 945 are 3 x 3 x 3 x 5 x 7

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

Given numbers are 478, 817, 402, 945

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

Apply this formula for all numbers.

Step1:

LCM(478, 817) = 390526

GCD(478, 817) = ( 478 x 817 ) / 390526

= 478 / 817

= 478

Step2:

LCM(1, 402) = 402

GCD(1, 402) = ( 1 x 402 ) / 402

= 1 / 402

= 1

Step3:

LCM(1, 945) = 945

GCD(1, 945) = ( 1 x 945 ) / 945

= 1 / 945

= 1

So, Greatest Common Divisor of 478, 817, 402, 945 is 1
