Given numbers are 781,418,268,953

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

The LCM of 781,418,268,953 is 3789939956.

Find LCM of 781,418,268,953 with Prime Factorization

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

2 x 11 x 71 x 19 x 134 x 953 = 3789939956

Therefore, the lowest common multiple of 781,418,268,953 is 3789939956.

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.

781 x 418 x 268 x 953 = 83378679032

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.

781 : 1, 11, 71, 781

418 : 1, 2, 11, 19, 22, 38, 209, 418

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

953 : 1, 953

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,418,268,953, is 1.

Now, the common factors can be found like this.

781:11x 71

418:2x 11x 19

268:2x 2x 67

953:953

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

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 83378679032/(1x22)

LCM = 83378679032/22

LCM = 3789939956

Thus, we can understand that the LCM of 781,418,268,953 is 3789939956.
