Given numbers are 291,324,622,780

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

The LCM of 291,324,622,780 is 635317020.

Find LCM of 291,324,622,780 with Prime Factorization

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

2 x 2 x 3 x 97 x 27 x 311 x 65 = 635317020

Therefore, the lowest common multiple of 291,324,622,780 is 635317020.

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.

291 x 324 x 622 x 780 = 45742825440

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.

291 : 1, 3, 97, 291

324 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 324

622 : 1, 2, 311, 622

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 291,324,622,780, is 1.

Now, the common factors can be found like this.

291:3x 97

324:2x 2x 3x 3x 3x 3

622:2x 311

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 2x 2x 3x 3 = 72

Therefore, the value for common factors is 72.

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 = 45742825440/(1x72)

LCM = 45742825440/72

LCM = 635317020

Thus, we can understand that the LCM of 291,324,622,780 is 635317020.
