Given numbers are 418,19,638,279

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

The LCM of 418,19,638,279 is 3382038.

Find LCM of 418,19,638,279 with Prime Factorization

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

2 x 11 x 19 x 1 x 1 x 29 x 279 = 3382038

Therefore, the lowest common multiple of 418,19,638,279 is 3382038.

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.

418 x 19 x 638 x 279 = 1413691884

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.

418 : 1, 2, 11, 19, 22, 38, 209, 418

19 : 1, 19

638 : 1, 2, 11, 22, 29, 58, 319, 638

279 : 1, 3, 9, 31, 93, 279

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 418,19,638,279, is 1.

Now, the common factors can be found like this.

418:2x 11x 19

19:19

638:2x 11x 29

279:3x 3x 31

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

2x 11x 19 = 418

Therefore, the value for common factors is 418.

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 = 1413691884/(1x418)

LCM = 1413691884/418

LCM = 3382038

Thus, we can understand that the LCM of 418,19,638,279 is 3382038.
