Given numbers are 815,851,821,212,868

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

The LCM of 815,851,821,212,868 is 26195453457460.

Find LCM of 815,851,821,212,868 with Prime Factorization

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

2 x 2 x 815 x 851 x 821 x 53 x 217 = 26195453457460

Therefore, the lowest common multiple of 815,851,821,212,868 is 26195453457460.

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.

815 x 851 x 821 x 212 x 868 = 104781813829840

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.

815 : 1, 5, 163, 815

851 : 1, 23, 37, 851

821 : 1, 821

212 : 1, 2, 4, 53, 106, 212

868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 815,851,821,212,868, is 1.

Now, the common factors can be found like this.

815:5x 163

851:23x 37

821:821

212:2x 2x 53

868:2x 2x 7x 31

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 104781813829840/(1x4)

LCM = 104781813829840/4

LCM = 26195453457460

Thus, we can understand that the LCM of 815,851,821,212,868 is 26195453457460.
