Given numbers are 290,209,446,423

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

The LCM of 290,209,446,423 is 5717280690.

Find LCM of 290,209,446,423 with Prime Factorization

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

2 x 145 x 209 x 223 x 423 = 5717280690

Therefore, the lowest common multiple of 290,209,446,423 is 5717280690.

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.

290 x 209 x 446 x 423 = 11434561380

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.

290 : 1, 2, 5, 10, 29, 58, 145, 290

209 : 1, 11, 19, 209

446 : 1, 2, 223, 446

423 : 1, 3, 9, 47, 141, 423

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 290,209,446,423, is 1.

Now, the common factors can be found like this.

290:2x 5x 29

209:11x 19

446:2x 223

423:3x 3x 47

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

2 = 2

Therefore, the value for common factors is 2.

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 = 11434561380/(1x2)

LCM = 11434561380/2

LCM = 5717280690

Thus, we can understand that the LCM of 290,209,446,423 is 5717280690.
