Given numbers are 909,787,138,213

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

The LCM of 909,787,138,213 is 2336440878.

Find LCM of 909,787,138,213 with Prime Factorization

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

3 x 303 x 787 x 46 x 71 = 2336440878

Therefore, the lowest common multiple of 909,787,138,213 is 2336440878.

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.

909 x 787 x 138 x 213 = 21027967902

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.

909 : 1, 3, 9, 101, 303, 909

787 : 1, 787

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

213 : 1, 3, 71, 213

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 909,787,138,213, is 1.

Now, the common factors can be found like this.

909:3x 3x 101

787:787

138:2x 3x 23

213:3x 71

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

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 21027967902/(1x9)

LCM = 21027967902/9

LCM = 2336440878

Thus, we can understand that the LCM of 909,787,138,213 is 2336440878.
