Given numbers are 247,712,268,921

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

The LCM of 247,712,268,921 is 10852039848.

Find LCM of 247,712,268,921 with Prime Factorization

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

2 x 2 x 247 x 178 x 67 x 921 = 10852039848

Therefore, the lowest common multiple of 247,712,268,921 is 10852039848.

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.

247 x 712 x 268 x 921 = 43408159392

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.

247 : 1, 13, 19, 247

712 : 1, 2, 4, 8, 89, 178, 356, 712

268 : 1, 2, 4, 67, 134, 268

921 : 1, 3, 307, 921

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 247,712,268,921, is 1.

Now, the common factors can be found like this.

247:13x 19

712:2x 2x 2x 89

268:2x 2x 67

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.

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 43408159392/(1x4)

LCM = 43408159392/4

LCM = 10852039848

Thus, we can understand that the LCM of 247,712,268,921 is 10852039848.
