Given numbers are 781,701,921,286

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

The LCM of 781,701,921,286 is 13109980026.

Find LCM of 781,701,921,286 with Prime Factorization

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

11 x 71 x 701 x 921 x 26 = 13109980026

Therefore, the lowest common multiple of 781,701,921,286 is 13109980026.

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 701 x 921 x 286 = 144209780286

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

701 : 1, 701

921 : 1, 3, 307, 921

286 : 1, 2, 11, 13, 22, 26, 143, 286

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,701,921,286, is 1.

Now, the common factors can be found like this.

781:11x 71

701:701

921:3x 307

286:2x 11x 13

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

11 = 11

Therefore, the value for common factors is 11.

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 = 144209780286/(1x11)

LCM = 144209780286/11

LCM = 13109980026

Thus, we can understand that the LCM of 781,701,921,286 is 13109980026.
