Given numbers are 405, 380, 54, 770

The list of prime factors of all numbers are

Prime factors of 405 are 3 x 3 x 3 x 3 x 5

Prime factors of 380 are 2 x 2 x 5 x 19

Prime factors of 54 are 2 x 3 x 3 x 3

Prime factors of 770 are 2 x 5 x 7 x 11

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

Given numbers are 405, 380, 54, 770

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

Apply this formula for all numbers.

Step1:

LCM(405, 380) = 30780

GCD(405, 380) = ( 405 x 380 ) / 30780

= 405 / 380

= 405

Step2:

LCM(5, 54) = 270

GCD(5, 54) = ( 5 x 54 ) / 270

= 5 / 54

= 5

Step3:

LCM(1, 770) = 770

GCD(1, 770) = ( 1 x 770 ) / 770

= 1 / 770

= 1

So, Greatest Common Divisor of 405, 380, 54, 770 is 1
