Given numbers are 399,506,221,781,341

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

The LCM of 399,506,221,781,341 is 98205481374.

Find LCM of 399,506,221,781,341 with Prime Factorization

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

11 x 399 x 46 x 221 x 71 x 31 = 98205481374

Therefore, the lowest common multiple of 399,506,221,781,341 is 98205481374.

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.

399 x 506 x 221 x 781 x 341 = 11882863246254

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.

399 : 1, 3, 7, 19, 21, 57, 133, 399

506 : 1, 2, 11, 22, 23, 46, 253, 506

221 : 1, 13, 17, 221

781 : 1, 11, 71, 781

341 : 1, 11, 31, 341

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 399,506,221,781,341, is 1.

Now, the common factors can be found like this.

399:3x 7x 19

506:2x 11x 23

221:13x 17

781:11x 71

341:11x 31

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

11x 11 = 121

Therefore, the value for common factors is 121.

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 = 11882863246254/(1x121)

LCM = 11882863246254/121

LCM = 98205481374

Thus, we can understand that the LCM of 399,506,221,781,341 is 98205481374.
