Given numbers are 691,552,989

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

The LCM of 691,552,989 is 16401576.

Find LCM of 691,552,989 with Prime Factorization

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

23 x 691 x 24 x 43 = 16401576

Therefore, the lowest common multiple of 691,552,989 is 16401576.

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.

691 x 552 x 989 = 377236248

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.

691 : 1, 691

552 : 1, 2, 3, 4, 6, 8, 12, 23, 24, 46, 69, 92, 138, 184, 276, 552

989 : 1, 23, 43, 989

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 691,552,989, is 1.

Now, the common factors can be found like this.

691:691

552:2x 2x 2x 3x 23

989:23x 43

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

23 = 23

Therefore, the value for common factors is 23.

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 = 377236248/(1x23)

LCM = 377236248/23

LCM = 16401576

Thus, we can understand that the LCM of 691,552,989 is 16401576.

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

• LCM of 920, 305, 502
