Given numbers are 285,145,815,778

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

The LCM of 285,145,815,778 is 1048117710.

Find LCM of 285,145,815,778 with Prime Factorization

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

5 x 57 x 29 x 163 x 778 = 1048117710

Therefore, the lowest common multiple of 285,145,815,778 is 1048117710.

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.

285 x 145 x 815 x 778 = 26202942750

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.

285 : 1, 3, 5, 15, 19, 57, 95, 285

145 : 1, 5, 29, 145

815 : 1, 5, 163, 815

778 : 1, 2, 389, 778

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 285,145,815,778, is 1.

Now, the common factors can be found like this.

285:3x 5x 19

145:5x 29

815:5x 163

778:2x 389

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

5x 5 = 25

Therefore, the value for common factors is 25.

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 = 26202942750/(1x25)

LCM = 26202942750/25

LCM = 1048117710

Thus, we can understand that the LCM of 285,145,815,778 is 1048117710.
