Given numbers are 891,397,319,974

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

The LCM of 891,397,319,974 is 9991372842.

Find LCM of 891,397,319,974 with Prime Factorization

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

11 x 81 x 397 x 29 x 974 = 9991372842

Therefore, the lowest common multiple of 891,397,319,974 is 9991372842.

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.

891 x 397 x 319 x 974 = 109905101262

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.

891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891

397 : 1, 397

319 : 1, 11, 29, 319

974 : 1, 2, 487, 974

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 891,397,319,974, is 1.

Now, the common factors can be found like this.

891:3x 3x 3x 3x 11

397:397

319:11x 29

974:2x 487

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

11 = 11

Therefore, the value for common factors is 11.

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 = 109905101262/(1x11)

LCM = 109905101262/11

LCM = 9991372842

Thus, we can understand that the LCM of 891,397,319,974 is 9991372842.
