Given numbers are 630,332,278,454,381

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

The LCM of 630,332,278,454,381 is 419076217980.

Find LCM of 630,332,278,454,381 with Prime Factorization

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

2 x 3 x 105 x 166 x 139 x 227 x 127 = 419076217980

Therefore, the lowest common multiple of 630,332,278,454,381 is 419076217980.

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.

630 x 332 x 278 x 454 x 381 = 10057829231520

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.

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

332 : 1, 2, 4, 83, 166, 332

278 : 1, 2, 139, 278

454 : 1, 2, 227, 454

381 : 1, 3, 127, 381

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 630,332,278,454,381, is 1.

Now, the common factors can be found like this.

630:2x 3x 3x 5x 7

332:2x 2x 83

278:2x 139

454:2x 227

381:3x 127

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

2x 2x 2x 3 = 24

Therefore, the value for common factors is 24.

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 = 10057829231520/(1x24)

LCM = 10057829231520/24

LCM = 419076217980

Thus, we can understand that the LCM of 630,332,278,454,381 is 419076217980.
