Given numbers are 724,298,385,691

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

The LCM of 724,298,385,691 is 28698791660.

Find LCM of 724,298,385,691 with Prime Factorization

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

2 x 362 x 149 x 385 x 691 = 28698791660

Therefore, the lowest common multiple of 724,298,385,691 is 28698791660.

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.

724 x 298 x 385 x 691 = 57397583320

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.

724 : 1, 2, 4, 181, 362, 724

298 : 1, 2, 149, 298

385 : 1, 5, 7, 11, 35, 55, 77, 385

691 : 1, 691

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 724,298,385,691, is 1.

Now, the common factors can be found like this.

724:2x 2x 181

298:2x 149

385:5x 7x 11

691:691

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 = 57397583320/(1x2)

LCM = 57397583320/2

LCM = 28698791660

Thus, we can understand that the LCM of 724,298,385,691 is 28698791660.
