Given numbers are 210,778,406,857

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

The LCM of 210,778,406,857 is 2030241570.

Find LCM of 210,778,406,857 with Prime Factorization

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

2 x 7 x 15 x 389 x 29 x 857 = 2030241570

Therefore, the lowest common multiple of 210,778,406,857 is 2030241570.

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.

210 x 778 x 406 x 857 = 56846763960

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.

210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210

778 : 1, 2, 389, 778

406 : 1, 2, 7, 14, 29, 58, 203, 406

857 : 1, 857

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 210,778,406,857, is 1.

Now, the common factors can be found like this.

210:2x 3x 5x 7

778:2x 389

406:2x 7x 29

857:857

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 7 = 28

Therefore, the value for common factors is 28.

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 = 56846763960/(1x28)

LCM = 56846763960/28

LCM = 2030241570

Thus, we can understand that the LCM of 210,778,406,857 is 2030241570.
