Given numbers are 126, 427, 817, 445

The list of prime factors of all numbers are

Prime factors of 126 are 2 x 3 x 3 x 7

Prime factors of 427 are 7 x 61

Prime factors of 817 are 19 x 43

Prime factors of 445 are 5 x 89

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

Given numbers are 126, 427, 817, 445

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

Apply this formula for all numbers.

Step1:

LCM(126, 427) = 7686

GCD(126, 427) = ( 126 x 427 ) / 7686

= 126 / 427

= 126

Step2:

LCM(7, 817) = 5719

GCD(7, 817) = ( 7 x 817 ) / 5719

= 7 / 817

= 7

Step3:

LCM(1, 445) = 445

GCD(1, 445) = ( 1 x 445 ) / 445

= 1 / 445

= 1

So, Greatest Common Divisor of 126, 427, 817, 445 is 1
