Given numbers are 787,438,260,943

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

The LCM of 787,438,260,943 is 42257508540.

Find LCM of 787,438,260,943 with Prime Factorization

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

2 x 787 x 219 x 130 x 943 = 42257508540

Therefore, the lowest common multiple of 787,438,260,943 is 42257508540.

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.

787 x 438 x 260 x 943 = 84515017080

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.

787 : 1, 787

438 : 1, 2, 3, 6, 73, 146, 219, 438

260 : 1, 2, 4, 5, 10, 13, 20, 26, 52, 65, 130, 260

943 : 1, 23, 41, 943

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 787,438,260,943, is 1.

Now, the common factors can be found like this.

787:787

438:2x 3x 73

260:2x 2x 5x 13

943:23x 41

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

2 = 2

Therefore, the value for common factors is 2.

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 = 84515017080/(1x2)

LCM = 84515017080/2

LCM = 42257508540

Thus, we can understand that the LCM of 787,438,260,943 is 42257508540.
