Given numbers are 391,388,453,118

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

The LCM of 391,388,453,118 is 4054699716.

Find LCM of 391,388,453,118 with Prime Factorization

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

2 x 391 x 194 x 453 x 59 = 4054699716

Therefore, the lowest common multiple of 391,388,453,118 is 4054699716.

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.

391 x 388 x 453 x 118 = 8109399432

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.

391 : 1, 17, 23, 391

388 : 1, 2, 4, 97, 194, 388

453 : 1, 3, 151, 453

118 : 1, 2, 59, 118

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,388,453,118, is 1.

Now, the common factors can be found like this.

391:17x 23

388:2x 2x 97

453:3x 151

118:2x 59

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 = 8109399432/(1x2)

LCM = 8109399432/2

LCM = 4054699716

Thus, we can understand that the LCM of 391,388,453,118 is 4054699716.
