Question

Calculate the difference between highest common factor and lowest common multiple of 12 and 30.

Answer 1

Step-by-step explanation:

Solution;

Factors:-

12 = 2 x 2x 3

30 = 2 x 3 x 5

Now, H.C.F. = 2 x 3 = 6

And L.C.M. = 6 x 2 x 5 = 60

By question;

H.C.F. - L.C.M. = 6 - 60 = -54

L.C.M. - H.C.F. = 60 - 6 = 54

Answer 2

Answer:

54

Step-by-step explanation:

LCM (12,30) we find: Prime factorization of 12 = 2 × 2 × 3 Prime factorization of 30 = 2 × 3 × 5 Using all prime numbers found as often as each occurs most often we take 2 × 2 × 3 × 5 = 60

Steps to find GCF

Find the prime factorization of 12

12 = 2 × 2 × 3

Find the prime factorization of 30

30 = 2 × 3 × 5

To find the gcf, multiply all the prime factors common to both numbers:

Therefore, GCF = 2 × 3

GCF = 6

therfore after subtracting the answer will be 54..
