Given numbers are 290,217,913,780

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

The LCM of 290,217,913,780 is 4481497020.

Find LCM of 290,217,913,780 with Prime Factorization

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

2 x 5 x 29 x 217 x 913 x 78 = 4481497020

Therefore, the lowest common multiple of 290,217,913,780 is 4481497020.

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 217 x 913 x 780 = 44814970200

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

217 : 1, 7, 31, 217

913 : 1, 11, 83, 913

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 290,217,913,780, is 1.

Now, the common factors can be found like this.

290:2x 5x 29

217:7x 31

913:11x 83

780:2x 2x 3x 5x 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 5 = 10

Therefore, the value for common factors is 10.

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 = 44814970200/(1x10)

LCM = 44814970200/10

LCM = 4481497020

Thus, we can understand that the LCM of 290,217,913,780 is 4481497020.
