Given numbers are 145, 855, 27, 924

The list of prime factors of all numbers are

Prime factors of 145 are 5 x 29

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

Prime factors of 27 are 3 x 3 x 3

Prime factors of 924 are 2 x 2 x 3 x 7 x 11

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

Given numbers are 145, 855, 27, 924

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

Apply this formula for all numbers.

Step1:

LCM(145, 855) = 24795

GCD(145, 855) = ( 145 x 855 ) / 24795

= 145 / 855

= 145

Step2:

LCM(5, 27) = 135

GCD(5, 27) = ( 5 x 27 ) / 135

= 5 / 27

= 5

Step3:

LCM(1, 924) = 924

GCD(1, 924) = ( 1 x 924 ) / 924

= 1 / 924

= 1

So, Greatest Common Divisor of 145, 855, 27, 924 is 1
