Calculate the LCM of 715,680,290,725

Given numbers are 715,680,290,725

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

The LCM of 715,680,290,725 is 14099800.

Find LCM of 715,680,290,725 with Prime Factorization


2 715, 680, 290, 725
5 715, 340, 145, 725
29 143, 68, 29, 145
143, 68, 1, 5

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

2 x 5 x 29 x 143 x 68 x 1 x 5 = 14099800

Therefore, the lowest common multiple of 715,680,290,725 is 14099800.

LCM Formula to Find Lowest Common Multiple of 715,680,290,725

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.

715 x 680 x 290 x 725 = 102223550000

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.

715 : 1, 5, 11, 13, 55, 65, 143, 715

680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680

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

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

5 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 715,680,290,725, is 5.

Now, the common factors can be found like this.

715:5x 11x 13

680:2x 2x 2x 5x 17

290:2x 5x 29

725:5x 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.

2x 5x 5x 29 = 1450

Therefore, the value for common factors is 1450.

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 = 102223550000/(5x1450)

LCM = 102223550000/7250

LCM = 14099800

Thus, we can understand that the LCM of 715,680,290,725 is 14099800.
