Given numbers are 391,858,116,214,172

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

The LCM of 391,858,116,214,172 is 89524988124.

Find LCM of 391,858,116,214,172 with Prime Factorization

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

2 x 2 x 391 x 429 x 29 x 107 x 43 = 89524988124

Therefore, the lowest common multiple of 391,858,116,214,172 is 89524988124.

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 858 x 116 x 214 x 172 = 1432399809984

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

858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858

116 : 1, 2, 4, 29, 58, 116

214 : 1, 2, 107, 214

172 : 1, 2, 4, 43, 86, 172

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,858,116,214,172, is 1.

Now, the common factors can be found like this.

391:17x 23

858:2x 3x 11x 13

116:2x 2x 29

214:2x 107

172:2x 2x 43

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 2 = 16

Therefore, the value for common factors is 16.

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 = 1432399809984/(1x16)

LCM = 1432399809984/16

LCM = 89524988124

Thus, we can understand that the LCM of 391,858,116,214,172 is 89524988124.
