Given numbers are 676,910,390,638

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

The LCM of 676,910,390,638 is 22642620.

Find LCM of 676,910,390,638 with Prime Factorization

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

2 x 5 x 13 x 26 x 7 x 3 x 319 = 22642620

Therefore, the lowest common multiple of 676,910,390,638 is 22642620.

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.

676 x 910 x 390 x 638 = 153064111200

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.

676 : 1, 2, 4, 13, 26, 52, 169, 338, 676

910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

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

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 676,910,390,638, is 2.

Now, the common factors can be found like this.

676:2x 2x 13x 13

910:2x 5x 7x 13

390:2x 3x 5x 13

638:2x 11x 29

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 5x 13x 13 = 3380

Therefore, the value for common factors is 3380.

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 = 153064111200/(2x3380)

LCM = 153064111200/6760

LCM = 22642620

Thus, we can understand that the LCM of 676,910,390,638 is 22642620.
