Given numbers are 781,220,759

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

The LCM of 781,220,759 is 1077780.

Find LCM of 781,220,759 with Prime Factorization

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

11 x 71 x 20 x 69 = 1077780

Therefore, the lowest common multiple of 781,220,759 is 1077780.

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 220 x 759 = 130411380

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

220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220

759 : 1, 3, 11, 23, 33, 69, 253, 759

11 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,220,759, is 11.

Now, the common factors can be found like this.

781:11x 71

220:2x 2x 5x 11

759:3x 11x 23

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 = 130411380/(11x11)

LCM = 130411380/121

LCM = 1077780

Thus, we can understand that the LCM of 781,220,759 is 1077780.
