Given numbers are 761,298,556,490

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

The LCM of 761,298,556,490 is 15445849580.

Find LCM of 761,298,556,490 with Prime Factorization

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

2 x 761 x 149 x 278 x 245 = 15445849580

Therefore, the lowest common multiple of 761,298,556,490 is 15445849580.

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.

761 x 298 x 556 x 490 = 61783398320

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.

761 : 1, 761

298 : 1, 2, 149, 298

556 : 1, 2, 4, 139, 278, 556

490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 761,298,556,490, is 1.

Now, the common factors can be found like this.

761:761

298:2x 149

556:2x 2x 139

490:2x 5x 7x 7

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 61783398320/(1x4)

LCM = 61783398320/4

LCM = 15445849580

Thus, we can understand that the LCM of 761,298,556,490 is 15445849580.
