Question

the HCF of two numbers is 5, theirs LCM is 60 and one of the number is 15.find The other numbers?​

Answer 1

Step-by-step explanation:

Given

• HCF
• LCM
• One number

To Find:

• The other number

Solution:

Other number = HCF×LCM/Given number

→5×60/15

→300/15

Other number

→20

Answer 2

Answer:

2 is 15

Step-by-step explanation:

We know that

The relation between H.C.F. and L.C.M. and two numbers is

H.C.F. x L.C.M. = Number 1st x Number 2nd

Given that,

H.C.F. = 5

L.C.M. = 60

Number 1=20

So,

5×60=20×Number 2nd

300=20×Number 2nd

Number 2nd=15

Hence the number 2 is 15
