Given numbers are 416,247,221,391

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

The LCM of 416,247,221,391 is 3090464.

Find LCM of 416,247,221,391 with Prime Factorization

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

13 x 17 x 32 x 19 x 1 x 23 = 3090464

Therefore, the lowest common multiple of 416,247,221,391 is 3090464.

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.

416 x 247 x 221 x 391 = 8878903072

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.

416 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 104, 208, 416

247 : 1, 13, 19, 247

221 : 1, 13, 17, 221

391 : 1, 17, 23, 391

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 416,247,221,391, is 1.

Now, the common factors can be found like this.

416:2x 2x 2x 2x 2x 13

247:13x 19

221:13x 17

391:17x 23

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

13x 13x 17 = 2873

Therefore, the value for common factors is 2873.

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 = 8878903072/(1x2873)

LCM = 8878903072/2873

LCM = 3090464

Thus, we can understand that the LCM of 416,247,221,391 is 3090464.
