Question

Numbers A, B and C are integral multiples of 3, 5 and 7 respectively.
If A>C> 17, then the lowest possible common multiple of all the three i.e., A, B
and Cis​

Answer 1

Answer:

105

Step-by-step explanation:

since A,B and C are integral multiples of 3,5 and 7

the LCM of A,B and C would be 3x5x7=105

Answer 2

Concept:

In mathematics, Least Common Multiple is referred to by its entire name, whereas Highest Common Factor is its complete name. The L.C.M. defines the least number that is exactly divisible by two or more numbers, whereas the H.C.F. describes the biggest factor existing between any given pair of two or more numbers. LCM is also known as the Least Common Multiple (LCM), and HCF is also known as the Greatest Common Factor (GCF).

We have two key techniques—the division method and the prime factorization approach—for determining H.C.F. and L.C.M.

Given:

Numbers A, B and C are integral multiples of 3, 5 and 7 respectively.

If A>C> 17

Find:

Find the lowest possible common multiple of all the three i.e., A, B

and C?

Solution:

We need to find the lcm of 3,5,7

3=3x1

5=5x1

7=7x1

Lcm be 3x5x7 =105

So, the lowest common multiple be 105
