Given numbers are 609,442,170,919

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

The LCM of 609,442,170,919 is 1236872910.

Find LCM of 609,442,170,919 with Prime Factorization

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

2 x 17 x 609 x 13 x 5 x 919 = 1236872910

Therefore, the lowest common multiple of 609,442,170,919 is 1236872910.

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.

609 x 442 x 170 x 919 = 42053678940

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.

609 : 1, 3, 7, 21, 29, 87, 203, 609

442 : 1, 2, 13, 17, 26, 34, 221, 442

170 : 1, 2, 5, 10, 17, 34, 85, 170

919 : 1, 919

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 609,442,170,919, is 1.

Now, the common factors can be found like this.

609:3x 7x 29

442:2x 13x 17

170:2x 5x 17

919:919

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

2x 17 = 34

Therefore, the value for common factors is 34.

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 = 42053678940/(1x34)

LCM = 42053678940/34

LCM = 1236872910

Thus, we can understand that the LCM of 609,442,170,919 is 1236872910.
