Given numbers are 725,731,420,226

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

The LCM of 725,731,420,226 is 5030522700.

Find LCM of 725,731,420,226 with Prime Factorization

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

2 x 5 x 145 x 731 x 42 x 113 = 5030522700

Therefore, the lowest common multiple of 725,731,420,226 is 5030522700.

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.

725 x 731 x 420 x 226 = 50305227000

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.

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

731 : 1, 17, 43, 731

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

226 : 1, 2, 113, 226

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 725,731,420,226, is 1.

Now, the common factors can be found like this.

725:5x 5x 29

731:17x 43

420:2x 2x 3x 5x 7

226:2x 113

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 50305227000/(1x10)

LCM = 50305227000/10

LCM = 5030522700

Thus, we can understand that the LCM of 725,731,420,226 is 5030522700.
