Given numbers are 845, 420, 844, 480

The list of prime factors of all numbers are

Prime factors of 845 are 5 x 13 x 13

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 844 are 2 x 2 x 211

Prime factors of 480 are 2 x 2 x 2 x 2 x 2 x 3 x 5

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

Given numbers are 845, 420, 844, 480

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

Apply this formula for all numbers.

Step1:

LCM(845, 420) = 70980

GCD(845, 420) = ( 845 x 420 ) / 70980

= 845 / 420

= 845

Step2:

LCM(5, 844) = 4220

GCD(5, 844) = ( 5 x 844 ) / 4220

= 5 / 844

= 5

Step3:

LCM(1, 480) = 480

GCD(1, 480) = ( 1 x 480 ) / 480

= 1 / 480

= 1

So, Greatest Common Divisor of 845, 420, 844, 480 is 1
