Given numbers are 3642,7078

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

The LCM of 3642,7078 is 12889038.

Find LCM of 3642,7078 with Prime Factorization

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

2 x 1821 x 3539 = 12889038

Therefore, the lowest common multiple of 3642,7078 is 12889038.

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.

3642 x 7078 = 25778076

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.

3642 : 1, 2, 3, 6, 607, 1214, 1821, 3642

7078 : 1, 2, 3539, 7078

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 3642,7078, is 2.

Now, the common factors can be found like this.

3642:2x 3x 607

7078:2x 3539

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 = 25778076/(2x1)

LCM = 25778076/2

LCM = 12889038

Thus, we can understand that the LCM of 3642,7078 is 12889038.
