Given numbers are 442,998,630

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

The LCM of 442,998,630 is 69475770.

Find LCM of 442,998,630 with Prime Factorization

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

2 x 221 x 499 x 315 = 69475770

Therefore, the lowest common multiple of 442,998,630 is 69475770.

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.

442 x 998 x 630 = 277903080

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.

442 : 1, 2, 13, 17, 26, 34, 221, 442

998 : 1, 2, 499, 998

630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 442,998,630, is 2.

Now, the common factors can be found like this.

442:2x 13x 17

998:2x 499

630:2x 3x 3x 5x 7

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

2 = 2

Therefore, the value for common factors is 2.

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 = 277903080/(2x2)

LCM = 277903080/4

LCM = 69475770

Thus, we can understand that the LCM of 442,998,630 is 69475770.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 231, 847, 531
