Given numbers are 891,160,842,890,190

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

The LCM of 891,160,842,890,190 is 101490032160.

Find LCM of 891,160,842,890,190 with Prime Factorization

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

2 x 5 x 891 x 16 x 421 x 89 x 19 = 101490032160

Therefore, the lowest common multiple of 891,160,842,890,190 is 101490032160.

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.

891 x 160 x 842 x 890 x 190 = 20298006432000

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.

891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891

160 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160

842 : 1, 2, 421, 842

890 : 1, 2, 5, 10, 89, 178, 445, 890

190 : 1, 2, 5, 10, 19, 38, 95, 190

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 891,160,842,890,190, is 1.

Now, the common factors can be found like this.

891:3x 3x 3x 3x 11

160:2x 2x 2x 2x 2x 5

842:2x 421

890:2x 5x 89

190:2x 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 2x 5x 5 = 200

Therefore, the value for common factors is 200.

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 = 20298006432000/(1x200)

LCM = 20298006432000/200

LCM = 101490032160

Thus, we can understand that the LCM of 891,160,842,890,190 is 101490032160.
