Given numbers are 715,688,706

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

The LCM of 715,688,706 is 173647760.

Find LCM of 715,688,706 with Prime Factorization

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

2 x 715 x 344 x 353 = 173647760

Therefore, the lowest common multiple of 715,688,706 is 173647760.

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 688 x 706 = 347295520

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

688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688

706 : 1, 2, 353, 706

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 715,688,706, is 1.

Now, the common factors can be found like this.

715:5x 11x 13

688:2x 2x 2x 2x 43

706:2x 353

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

2 = 2

Therefore, the value for common factors is 2.

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 = 347295520/(1x2)

LCM = 347295520/2

LCM = 173647760

Thus, we can understand that the LCM of 715,688,706 is 173647760.

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