Given numbers are 6458,1660

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 6458,1660 is 5360140.

Find LCM of 6458,1660 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 3229 x 830 = 5360140

Therefore, the lowest common multiple of 6458,1660 is 5360140.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

6458 x 1660 = 10720280

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

6458 : 1, 2, 3229, 6458

1660 : 1, 2, 4, 5, 10, 20, 83, 166, 332, 415, 830, 1660

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 6458,1660, is 2.

Now, the common factors can be found like this.

6458:2x 3229

1660:2x 2x 5x 83

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

= 1

Therefore, the value for common factors is 1.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 10720280/(2x1)

LCM = 10720280/2

LCM = 5360140

Thus, we can understand that the LCM of 6458,1660 is 5360140.
