LCM of two prime numbers x and y is 187. Find the value of 2(x-y).
Answers
Answer:
12
Step-by-step explanation:
First the multiples of 187
So, we get the multiple as 17 &11
This is because 17 x 11 = 187
So consider that the value of x is 17 and y is 11
The value of 2(x-y) is
= 2(17-11)
= 2 x 6
= 12
Hence, the value is 12
Given lcm of two prime numbers x and y is 187.
To Find : value of 2(x-y)
Solution:
HCF of two different prime numbers is 1
LCM of two different prime numbers = their product
x*y = 187
187 = 1 * 187 not possible as 1 is not prime number
187 = 11 * 17
11 and 17 both are prime numbers
x = 11 and y = 17
=> 2(x - y) = 2(11 - 17) = - 12
x = 17 and y = 11
2(17 - 11) = 12
value of 2(x-y) = ± 12
