Question

L.c.m of two prime numbers is 161.Find their Sum

Answer 1

Step-by-step explanation:

L.C.M of two prime numbers x and y is 161.

Prime factorization of 161 = 7, 23

So, the two prime numbers are 7 and 23.

where x = 7 and y = 23 or x = 23 and y = 7

We have to find the value of 3y - x

If x = 7 and y = 23

Then the value of 3y - x

(3*23) - 7

= 69 - 7

= 62

If x = 23 and y = 7

Then, the value of 3y - x

3*7 - 23

= 21 - 23

= - 2
