Given numbers are 262, 390, 517, 405

The list of prime factors of all numbers are

Prime factors of 262 are 2 x 131

Prime factors of 390 are 2 x 3 x 5 x 13

Prime factors of 517 are 11 x 47

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

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

Given numbers are 262, 390, 517, 405

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

Apply this formula for all numbers.

Step1:

LCM(262, 390) = 51090

GCD(262, 390) = ( 262 x 390 ) / 51090

= 262 / 390

= 262

Step2:

LCM(2, 517) = 1034

GCD(2, 517) = ( 2 x 517 ) / 1034

= 2 / 517

= 2

Step3:

LCM(1, 405) = 405

GCD(1, 405) = ( 1 x 405 ) / 405

= 1 / 405

= 1

So, Greatest Common Divisor of 262, 390, 517, 405 is 1
