Given numbers are 725,518,161,821

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

The LCM of 725,518,161,821 is 7091510650.

Find LCM of 725,518,161,821 with Prime Factorization

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

7 x 725 x 74 x 23 x 821 = 7091510650

Therefore, the lowest common multiple of 725,518,161,821 is 7091510650.

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 518 x 161 x 821 = 49640574550

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

518 : 1, 2, 7, 14, 37, 74, 259, 518

161 : 1, 7, 23, 161

821 : 1, 821

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 725,518,161,821, is 1.

Now, the common factors can be found like this.

725:5x 5x 29

518:2x 7x 37

161:7x 23

821:821

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

7 = 7

Therefore, the value for common factors is 7.

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 = 49640574550/(1x7)

LCM = 49640574550/7

LCM = 7091510650

Thus, we can understand that the LCM of 725,518,161,821 is 7091510650.
