Given numbers are 781,220,867,509

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

The LCM of 781,220,867,509 is 6893152860.

Find LCM of 781,220,867,509 with Prime Factorization

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

11 x 71 x 20 x 867 x 509 = 6893152860

Therefore, the lowest common multiple of 781,220,867,509 is 6893152860.

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 867 x 509 = 75824681460

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

867 : 1, 3, 17, 51, 289, 867

509 : 1, 509

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,220,867,509, is 1.

Now, the common factors can be found like this.

781:11x 71

220:2x 2x 5x 11

867:3x 17x 17

509:509

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 = 75824681460/(1x11)

LCM = 75824681460/11

LCM = 6893152860

Thus, we can understand that the LCM of 781,220,867,509 is 6893152860.
