Given numbers are 679,989,138

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

The LCM of 679,989,138 is 4029186.

Find LCM of 679,989,138 with Prime Factorization

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

23 x 679 x 43 x 6 = 4029186

Therefore, the lowest common multiple of 679,989,138 is 4029186.

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.

679 x 989 x 138 = 92671278

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.

679 : 1, 7, 97, 679

989 : 1, 23, 43, 989

138 : 1, 2, 3, 6, 23, 46, 69, 138

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 679,989,138, is 1.

Now, the common factors can be found like this.

679:7x 97

989:23x 43

138:2x 3x 23

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 = 92671278/(1x23)

LCM = 92671278/23

LCM = 4029186

Thus, we can understand that the LCM of 679,989,138 is 4029186.

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

• LCM of 152, 467, 748
• LCM of 810, 701, 397
