Given numbers are 291,171,777,638,320

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

The LCM of 291,171,777,638,320 is 438539048640.

Find LCM of 291,171,777,638,320 with Prime Factorization

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

2 x 3 x 97 x 57 x 259 x 319 x 160 = 438539048640

Therefore, the lowest common multiple of 291,171,777,638,320 is 438539048640.

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 171 x 777 x 638 x 320 = 7893702875520

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

171 : 1, 3, 9, 19, 57, 171

777 : 1, 3, 7, 21, 37, 111, 259, 777

638 : 1, 2, 11, 22, 29, 58, 319, 638

320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 291,171,777,638,320, is 1.

Now, the common factors can be found like this.

291:3x 97

171:3x 3x 19

777:3x 7x 37

638:2x 11x 29

320:2x 2x 2x 2x 2x 2x 5

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

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 7893702875520/(1x18)

LCM = 7893702875520/18

LCM = 438539048640

Thus, we can understand that the LCM of 291,171,777,638,320 is 438539048640.
