Given numbers are 858,949,221,857

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

The LCM of 858,949,221,857 is 912514746.

Find LCM of 858,949,221,857 with Prime Factorization

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

13 x 66 x 73 x 17 x 857 = 912514746

Therefore, the lowest common multiple of 858,949,221,857 is 912514746.

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.

858 x 949 x 221 x 857 = 154214992074

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.

858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858

949 : 1, 13, 73, 949

221 : 1, 13, 17, 221

857 : 1, 857

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 858,949,221,857, is 1.

Now, the common factors can be found like this.

858:2x 3x 11x 13

949:13x 73

221:13x 17

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.

13x 13 = 169

Therefore, the value for common factors is 169.

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 = 154214992074/(1x169)

LCM = 154214992074/169

LCM = 912514746

Thus, we can understand that the LCM of 858,949,221,857 is 912514746.
