Question

25,35,40lcm by prime factorization​

Answer 1

Answer:

1400

Step-by-step explanation

To find the least common multiple of two or more numbers is to first list down all the prime factors of each number just like that:

25= 5×5

35= 5×7

40= 2×2×2×5

Then multiply each of the factors the greatest number of times it occurs in either number. If the same factor occurs more than once in every number, you multiply the factor the greatest number of times it occurs.

Let's see what we meant by this statement:

2: three occurrence

5: two occurrence

7: one occurrence

Therefore, LCM of 25, 35, 40 = 2×2×2×5×5×7=1400.
