Given numbers are 290,290,641,308,305

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

The LCM of 290,290,641,308,305 is 1746250660.

Find LCM of 290,290,641,308,305 with Prime Factorization

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

2 x 5 x 29 x 1 x 1 x 641 x 154 x 61 = 1746250660

Therefore, the lowest common multiple of 290,290,641,308,305 is 1746250660.

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 290 x 641 x 308 x 305 = 5064126914000

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

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

641 : 1, 641

308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308

305 : 1, 5, 61, 305

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 290,290,641,308,305, is 1.

Now, the common factors can be found like this.

290:2x 5x 29

290:2x 5x 29

641:641

308:2x 2x 7x 11

305:5x 61

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 5x 5x 29 = 2900

Therefore, the value for common factors is 2900.

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 = 5064126914000/(1x2900)

LCM = 5064126914000/2900

LCM = 1746250660

Thus, we can understand that the LCM of 290,290,641,308,305 is 1746250660.
