Given numbers are 397,238,920,391

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

The LCM of 397,238,920,391 is 43463560.

Find LCM of 397,238,920,391 with Prime Factorization

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

2 x 17 x 23 x 397 x 7 x 20 x 1 = 43463560

Therefore, the lowest common multiple of 397,238,920,391 is 43463560.

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.

397 x 238 x 920 x 391 = 33988503920

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.

397 : 1, 397

238 : 1, 2, 7, 14, 17, 34, 119, 238

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

391 : 1, 17, 23, 391

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 397,238,920,391, is 1.

Now, the common factors can be found like this.

397:397

238:2x 7x 17

920:2x 2x 2x 5x 23

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.

2x 17x 23 = 782

Therefore, the value for common factors is 782.

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 = 33988503920/(1x782)

LCM = 33988503920/782

LCM = 43463560

Thus, we can understand that the LCM of 397,238,920,391 is 43463560.
