Given numbers are 769,442,725,646

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

The LCM of 769,442,725,646 is 4682094950.

Find LCM of 769,442,725,646 with Prime Factorization

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

2 x 17 x 769 x 13 x 725 x 19 = 4682094950

Therefore, the lowest common multiple of 769,442,725,646 is 4682094950.

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.

769 x 442 x 725 x 646 = 159191228300

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.

769 : 1, 769

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

725 : 1, 5, 25, 29, 145, 725

646 : 1, 2, 17, 19, 34, 38, 323, 646

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 769,442,725,646, is 1.

Now, the common factors can be found like this.

769:769

442:2x 13x 17

725:5x 5x 29

646:2x 17x 19

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 = 159191228300/(1x34)

LCM = 159191228300/34

LCM = 4682094950

Thus, we can understand that the LCM of 769,442,725,646 is 4682094950.
