Given numbers are 441, 138, 855, 775

The list of prime factors of all numbers are

Prime factors of 441 are 3 x 3 x 7 x 7

Prime factors of 138 are 2 x 3 x 23

Prime factors of 855 are 3 x 3 x 5 x 19

Prime factors of 775 are 5 x 5 x 31

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

Given numbers are 441, 138, 855, 775

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

Apply this formula for all numbers.

Step1:

LCM(441, 138) = 20286

GCD(441, 138) = ( 441 x 138 ) / 20286

= 441 / 138

= 441

Step2:

LCM(3, 855) = 855

GCD(3, 855) = ( 3 x 855 ) / 855

= 3 / 855

= 3

Step3:

LCM(3, 775) = 2325

GCD(3, 775) = ( 3 x 775 ) / 2325

= 3 / 775

= 3

So, Greatest Common Divisor of 441, 138, 855, 775 is 1
