Given numbers are 115, 161, 390, 362

The list of prime factors of all numbers are

Prime factors of 115 are 5 x 23

Prime factors of 161 are 7 x 23

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

Prime factors of 362 are 2 x 181

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

Given numbers are 115, 161, 390, 362

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

Apply this formula for all numbers.

Step1:

LCM(115, 161) = 805

GCD(115, 161) = ( 115 x 161 ) / 805

= 115 / 161

= 115

Step2:

LCM(23, 390) = 8970

GCD(23, 390) = ( 23 x 390 ) / 8970

= 23 / 390

= 23

Step3:

LCM(1, 362) = 362

GCD(1, 362) = ( 1 x 362 ) / 362

= 1 / 362

= 1

So, Greatest Common Divisor of 115, 161, 390, 362 is 1
