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
