Given numbers are 715,39,451

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

The LCM of 715,39,451 is 87945.

Find LCM of 715,39,451 with Prime Factorization

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

11 x 13 x 5 x 3 x 41 = 87945

Therefore, the lowest common multiple of 715,39,451 is 87945.

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 39 x 451 = 12576135

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

39 : 1, 3, 13, 39

451 : 1, 11, 41, 451

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 715,39,451, is 1.

Now, the common factors can be found like this.

715:5x 11x 13

39:3x 13

451:11x 41

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

11x 13 = 143

Therefore, the value for common factors is 143.

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 = 12576135/(1x143)

LCM = 12576135/143

LCM = 87945

Thus, we can understand that the LCM of 715,39,451 is 87945.

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