Given numbers are 721,287,597

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

The LCM of 721,287,597 is 17647917.

Find LCM of 721,287,597 with Prime Factorization

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

7 x 103 x 41 x 597 = 17647917

Therefore, the lowest common multiple of 721,287,597 is 17647917.

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.

721 x 287 x 597 = 123535419

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.

721 : 1, 7, 103, 721

287 : 1, 7, 41, 287

597 : 1, 3, 199, 597

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,287,597, is 1.

Now, the common factors can be found like this.

721:7x 103

287:7x 41

597:3x 199

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

7 = 7

Therefore, the value for common factors is 7.

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 = 123535419/(1x7)

LCM = 123535419/7

LCM = 17647917

Thus, we can understand that the LCM of 721,287,597 is 17647917.

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

• LCM of 480, 134, 496
• LCM of 231, 998, 716
