Given numbers are 989,989,921

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

The LCM of 989,989,921 is 910869.

Find LCM of 989,989,921 with Prime Factorization

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

23 x 43 x 1 x 1 x 921 = 910869

Therefore, the lowest common multiple of 989,989,921 is 910869.

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 989 x 921 = 900849441

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

989 : 1, 23, 43, 989

921 : 1, 3, 307, 921

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 989,989,921, is 1.

Now, the common factors can be found like this.

989:23x 43

989:23x 43

921:3x 307

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

23x 43 = 989

Therefore, the value for common factors is 989.

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 = 900849441/(1x989)

LCM = 900849441/989

LCM = 910869

Thus, we can understand that the LCM of 989,989,921 is 910869.

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

• LCM of 230, 763, 824
• LCM of 730, 571, 292
