Given numbers are 661,800,146,230,855

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

The LCM of 661,800,146,230,855 is 151823239200.

Find LCM of 661,800,146,230,855 with Prime Factorization

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

2 x 5 x 661 x 80 x 73 x 23 x 171 = 151823239200

Therefore, the lowest common multiple of 661,800,146,230,855 is 151823239200.

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.

661 x 800 x 146 x 230 x 855 = 15182323920000

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.

661 : 1, 661

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

146 : 1, 2, 73, 146

230 : 1, 2, 5, 10, 23, 46, 115, 230

855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 661,800,146,230,855, is 1.

Now, the common factors can be found like this.

661:661

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

146:2x 73

230:2x 5x 23

855:3x 3x 5x 19

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 5x 5 = 100

Therefore, the value for common factors is 100.

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 = 15182323920000/(1x100)

LCM = 15182323920000/100

LCM = 151823239200

Thus, we can understand that the LCM of 661,800,146,230,855 is 151823239200.
