Given numbers are 781,221,813,169

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

The LCM of 781,221,813,169 is 1824219969.

Find LCM of 781,221,813,169 with Prime Factorization

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

13 x 781 x 17 x 813 x 13 = 1824219969

Therefore, the lowest common multiple of 781,221,813,169 is 1824219969.

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 221 x 813 x 169 = 23714859597

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

221 : 1, 13, 17, 221

813 : 1, 3, 271, 813

169 : 1, 13, 169

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,221,813,169, is 1.

Now, the common factors can be found like this.

781:11x 71

221:13x 17

813:3x 271

169:13x 13

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

13 = 13

Therefore, the value for common factors is 13.

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 = 23714859597/(1x13)

LCM = 23714859597/13

LCM = 1824219969

Thus, we can understand that the LCM of 781,221,813,169 is 1824219969.
