Given numbers are 154,409,690,143

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

The LCM of 154,409,690,143 is 282492210.

Find LCM of 154,409,690,143 with Prime Factorization

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

2 x 11 x 7 x 409 x 345 x 13 = 282492210

Therefore, the lowest common multiple of 154,409,690,143 is 282492210.

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 409 x 690 x 143 = 6214828620

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

409 : 1, 409

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

143 : 1, 11, 13, 143

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 154,409,690,143, is 1.

Now, the common factors can be found like this.

154:2x 7x 11

409:409

690:2x 3x 5x 23

143:11x 13

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

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 6214828620/(1x22)

LCM = 6214828620/22

LCM = 282492210

Thus, we can understand that the LCM of 154,409,690,143 is 282492210.
