Given numbers are 700,800,186,621,455

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

The LCM of 700,800,186,621,455 is 1401472800.

Find LCM of 700,800,186,621,455 with Prime Factorization

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

2 x 2 x 3 x 5 x 5 x 7 x 1 x 8 x 31 x 207 x 13 = 1401472800

Therefore, the lowest common multiple of 700,800,186,621,455 is 1401472800.

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.

700 x 800 x 186 x 621 x 455 = 29430928800000

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.

700 : 1, 2, 4, 5, 7, 10, 14, 20, 25, 28, 35, 50, 70, 100, 140, 175, 350, 700

800 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, 800

186 : 1, 2, 3, 6, 31, 62, 93, 186

621 : 1, 3, 9, 23, 27, 69, 207, 621

455 : 1, 5, 7, 13, 35, 65, 91, 455

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 700,800,186,621,455, is 1.

Now, the common factors can be found like this.

700:2x 2x 5x 5x 7

800:2x 2x 2x 2x 2x 5x 5

186:2x 3x 31

621:3x 3x 3x 23

455:5x 7x 13

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 3x 5x 5x 5x 7 = 21000

Therefore, the value for common factors is 21000.

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 = 29430928800000/(1x21000)

LCM = 29430928800000/21000

LCM = 1401472800

Thus, we can understand that the LCM of 700,800,186,621,455 is 1401472800.
