Given numbers are 400,721,786,397

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

The LCM of 400,721,786,397 is 44996456400.

Find LCM of 400,721,786,397 with Prime Factorization

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

2 x 200 x 721 x 393 x 397 = 44996456400

Therefore, the lowest common multiple of 400,721,786,397 is 44996456400.

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.

400 x 721 x 786 x 397 = 89992912800

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.

400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400

721 : 1, 7, 103, 721

786 : 1, 2, 3, 6, 131, 262, 393, 786

397 : 1, 397

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 400,721,786,397, is 1.

Now, the common factors can be found like this.

400:2x 2x 2x 2x 5x 5

721:7x 103

786:2x 3x 131

397:397

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

2 = 2

Therefore, the value for common factors is 2.

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 = 89992912800/(1x2)

LCM = 89992912800/2

LCM = 44996456400

Thus, we can understand that the LCM of 400,721,786,397 is 44996456400.
