Given numbers are 115,715,457

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

The LCM of 115,715,457 is 7515365.

Find LCM of 115,715,457 with Prime Factorization

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

5 x 23 x 143 x 457 = 7515365

Therefore, the lowest common multiple of 115,715,457 is 7515365.

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.

115 x 715 x 457 = 37576825

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.

115 : 1, 5, 23, 115

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

457 : 1, 457

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 115,715,457, is 1.

Now, the common factors can be found like this.

115:5x 23

715:5x 11x 13

457:457

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

5 = 5

Therefore, the value for common factors is 5.

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 = 37576825/(1x5)

LCM = 37576825/5

LCM = 7515365

Thus, we can understand that the LCM of 115,715,457 is 7515365.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 679, 616, 618
• LCM of 661, 627, 647
• LCM of 199, 922, 642
