Given numbers are 825, 906, 420, 109

The list of prime factors of all numbers are

Prime factors of 825 are 3 x 5 x 5 x 11

Prime factors of 906 are 2 x 3 x 151

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

Prime factors of 109 are 109

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

Given numbers are 825, 906, 420, 109

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

Apply this formula for all numbers.

Step1:

LCM(825, 906) = 249150

GCD(825, 906) = ( 825 x 906 ) / 249150

= 825 / 906

= 825

Step2:

LCM(3, 420) = 420

GCD(3, 420) = ( 3 x 420 ) / 420

= 3 / 420

= 3

Step3:

LCM(3, 109) = 327

GCD(3, 109) = ( 3 x 109 ) / 327

= 3 / 109

= 3

So, Greatest Common Divisor of 825, 906, 420, 109 is 1
