Given numbers are 905, 990, 297, 427

The list of prime factors of all numbers are

Prime factors of 905 are 5 x 181

Prime factors of 990 are 2 x 3 x 3 x 5 x 11

Prime factors of 297 are 3 x 3 x 3 x 11

Prime factors of 427 are 7 x 61

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

Given numbers are 905, 990, 297, 427

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

Apply this formula for all numbers.

Step1:

LCM(905, 990) = 179190

GCD(905, 990) = ( 905 x 990 ) / 179190

= 905 / 990

= 905

Step2:

LCM(5, 297) = 1485

GCD(5, 297) = ( 5 x 297 ) / 1485

= 5 / 297

= 5

Step3:

LCM(1, 427) = 427

GCD(1, 427) = ( 1 x 427 ) / 427

= 1 / 427

= 1

So, Greatest Common Divisor of 905, 990, 297, 427 is 1
