Given numbers are 845, 685, 409, 612

The list of prime factors of all numbers are

Prime factors of 845 are 5 x 13 x 13

Prime factors of 685 are 5 x 137

Prime factors of 409 are 409

Prime factors of 612 are 2 x 2 x 3 x 3 x 17

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

Given numbers are 845, 685, 409, 612

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

Apply this formula for all numbers.

Step1:

LCM(845, 685) = 115765

GCD(845, 685) = ( 845 x 685 ) / 115765

= 845 / 685

= 845

Step2:

LCM(5, 409) = 2045

GCD(5, 409) = ( 5 x 409 ) / 2045

= 5 / 409

= 5

Step3:

LCM(1, 612) = 612

GCD(1, 612) = ( 1 x 612 ) / 612

= 1 / 612

= 1

So, Greatest Common Divisor of 845, 685, 409, 612 is 1
