Question

LCM of two prime numbers x and y is 221. Find 5(x-y).​

Answer 1

Answer:

-2

Step-by-step explanation:

161=7×23

So, x=23 and y=7

Therefore,

(3y−x)=(3×7−23)=−2

Answer 2

Answer:

72

Step-by-step explanation:

HCF = x and y = 1

Product of two number = LCM*HCF

x*y=221

x*y=13*17

y.=17 and x=13

5x-y=5(17)-13

85-13

=72
