Given numbers are 617,420,725,445

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

The LCM of 617,420,725,445 is 3344201700.

Find LCM of 617,420,725,445 with Prime Factorization

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

5 x 617 x 84 x 145 x 89 = 3344201700

Therefore, the lowest common multiple of 617,420,725,445 is 3344201700.

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.

617 x 420 x 725 x 445 = 83605042500

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.

617 : 1, 617

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

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

445 : 1, 5, 89, 445

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 617,420,725,445, is 1.

Now, the common factors can be found like this.

617:617

420:2x 2x 3x 5x 7

725:5x 5x 29

445:5x 89

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

5x 5 = 25

Therefore, the value for common factors is 25.

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 = 83605042500/(1x25)

LCM = 83605042500/25

LCM = 3344201700

Thus, we can understand that the LCM of 617,420,725,445 is 3344201700.
