Given numbers are 742,290,398,913

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

The LCM of 742,290,398,913 is 19547704330.

Find LCM of 742,290,398,913 with Prime Factorization

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

2 x 371 x 145 x 199 x 913 = 19547704330

Therefore, the lowest common multiple of 742,290,398,913 is 19547704330.

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.

742 x 290 x 398 x 913 = 78190817320

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.

742 : 1, 2, 7, 14, 53, 106, 371, 742

290 : 1, 2, 5, 10, 29, 58, 145, 290

398 : 1, 2, 199, 398

913 : 1, 11, 83, 913

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 742,290,398,913, is 1.

Now, the common factors can be found like this.

742:2x 7x 53

290:2x 5x 29

398:2x 199

913:11x 83

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 = 78190817320/(1x4)

LCM = 78190817320/4

LCM = 19547704330

Thus, we can understand that the LCM of 742,290,398,913 is 19547704330.
