Given numbers are 989,721,559

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

The LCM of 989,721,559 is 9269897.

Find LCM of 989,721,559 with Prime Factorization

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

43 x 23 x 721 x 13 = 9269897

Therefore, the lowest common multiple of 989,721,559 is 9269897.

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.

989 x 721 x 559 = 398605571

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.

989 : 1, 23, 43, 989

721 : 1, 7, 103, 721

559 : 1, 13, 43, 559

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 989,721,559, is 1.

Now, the common factors can be found like this.

989:23x 43

721:7x 103

559:13x 43

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

43 = 43

Therefore, the value for common factors is 43.

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 = 398605571/(1x43)

LCM = 398605571/43

LCM = 9269897

Thus, we can understand that the LCM of 989,721,559 is 9269897.

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

• LCM of 583, 608, 825
