Given numbers are 400,745,791,730

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

The LCM of 400,745,791,730 is 3441482800.

Find LCM of 400,745,791,730 with Prime Factorization

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

2 x 5 x 40 x 149 x 791 x 73 = 3441482800

Therefore, the lowest common multiple of 400,745,791,730 is 3441482800.

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 745 x 791 x 730 = 172074140000

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

745 : 1, 5, 149, 745

791 : 1, 7, 113, 791

730 : 1, 2, 5, 10, 73, 146, 365, 730

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 400,745,791,730, is 1.

Now, the common factors can be found like this.

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

745:5x 149

791:7x 113

730:2x 5x 73

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

2x 5x 5 = 50

Therefore, the value for common factors is 50.

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 = 172074140000/(1x50)

LCM = 172074140000/50

LCM = 3441482800

Thus, we can understand that the LCM of 400,745,791,730 is 3441482800.
