Given numbers are 312,974,208,646,782

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

The LCM of 312,974,208,646,782 is 2257583952.

Find LCM of 312,974,208,646,782 with Prime Factorization

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

2 x 2 x 2 x 13 x 17 x 3 x 487 x 2 x 19 x 23 = 2257583952

Therefore, the lowest common multiple of 312,974,208,646,782 is 2257583952.

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.

312 x 974 x 208 x 646 x 782 = 31931267417088

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.

312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312

974 : 1, 2, 487, 974

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

646 : 1, 2, 17, 19, 34, 38, 323, 646

782 : 1, 2, 17, 23, 34, 46, 391, 782

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 312,974,208,646,782, is 2.

Now, the common factors can be found like this.

312:2x 2x 2x 3x 13

974:2x 487

208:2x 2x 2x 2x 13

646:2x 17x 19

782:2x 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.

2x 2x 2x 2x 2x 13x 17 = 7072

Therefore, the value for common factors is 7072.

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 = 31931267417088/(2x7072)

LCM = 31931267417088/14144

LCM = 2257583952

Thus, we can understand that the LCM of 312,974,208,646,782 is 2257583952.
