Given numbers are 189,391,290,318

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

The LCM of 189,391,290,318 is 1135827630.

Find LCM of 189,391,290,318 with Prime Factorization

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

2 x 3 x 63 x 391 x 145 x 53 = 1135827630

Therefore, the lowest common multiple of 189,391,290,318 is 1135827630.

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.

189 x 391 x 290 x 318 = 6814965780

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.

189 : 1, 3, 7, 9, 21, 27, 63, 189

391 : 1, 17, 23, 391

290 : 1, 2, 5, 10, 29, 58, 145, 290

318 : 1, 2, 3, 6, 53, 106, 159, 318

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 189,391,290,318, is 1.

Now, the common factors can be found like this.

189:3x 3x 3x 7

391:17x 23

290:2x 5x 29

318:2x 3x 53

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 6814965780/(1x6)

LCM = 6814965780/6

LCM = 1135827630

Thus, we can understand that the LCM of 189,391,290,318 is 1135827630.
