Given numbers are 180,790,781,283,257

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

The LCM of 180,790,781,283,257 is 807737394420.

Find LCM of 180,790,781,283,257 with Prime Factorization

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

2 x 5 x 18 x 79 x 781 x 283 x 257 = 807737394420

Therefore, the lowest common multiple of 180,790,781,283,257 is 807737394420.

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.

180 x 790 x 781 x 283 x 257 = 8077373944200

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.

180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180

790 : 1, 2, 5, 10, 79, 158, 395, 790

781 : 1, 11, 71, 781

283 : 1, 283

257 : 1, 257

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 180,790,781,283,257, is 1.

Now, the common factors can be found like this.

180:2x 2x 3x 3x 5

790:2x 5x 79

781:11x 71

283:283

257:257

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 8077373944200/(1x10)

LCM = 8077373944200/10

LCM = 807737394420

Thus, we can understand that the LCM of 180,790,781,283,257 is 807737394420.
