Calculate the LCM of 725,399,455,290

Given numbers are 725,399,455,290

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

The LCM of 725,399,455,290 is 7521150.

Find LCM of 725,399,455,290 with Prime Factorization


5 725, 399, 455, 290
7 145, 399, 91, 58
29 145, 57, 13, 58
5, 57, 13, 2

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

5 x 7 x 29 x 5 x 57 x 13 x 2 = 7521150

Therefore, the lowest common multiple of 725,399,455,290 is 7521150.

LCM Formula to Find Lowest Common Multiple of 725,399,455,290

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 399 x 455 x 290 = 38169836250

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

399 : 1, 3, 7, 19, 21, 57, 133, 399

455 : 1, 5, 7, 13, 35, 65, 91, 455

290 : 1, 2, 5, 10, 29, 58, 145, 290

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 725,399,455,290, is 1.

Now, the common factors can be found like this.

725:5x 5x 29

399:3x 7x 19

455:5x 7x 13

290:2x 5x 29

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

5x 5x 7x 29 = 5075

Therefore, the value for common factors is 5075.

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 = 38169836250/(1x5075)

LCM = 38169836250/5075

LCM = 7521150

Thus, we can understand that the LCM of 725,399,455,290 is 7521150.
