Given numbers are 154,451,970,891,816

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

The LCM of 154,451,970,891,816 is 33734186640.

Find LCM of 154,451,970,891,816 with Prime Factorization

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

2 x 3 x 11 x 7 x 41 x 485 x 27 x 136 = 33734186640

Therefore, the lowest common multiple of 154,451,970,891,816 is 33734186640.

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.

154 x 451 x 970 x 891 x 816 = 48982039001280

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.

154 : 1, 2, 7, 11, 14, 22, 77, 154

451 : 1, 11, 41, 451

970 : 1, 2, 5, 10, 97, 194, 485, 970

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

816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 154,451,970,891,816, is 1.

Now, the common factors can be found like this.

154:2x 7x 11

451:11x 41

970:2x 5x 97

891:3x 3x 3x 3x 11

816:2x 2x 2x 2x 3x 17

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 3x 11x 11 = 1452

Therefore, the value for common factors is 1452.

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 = 48982039001280/(1x1452)

LCM = 48982039001280/1452

LCM = 33734186640

Thus, we can understand that the LCM of 154,451,970,891,816 is 33734186640.
