Given numbers are 230,422,857,642,980
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 230,422,857,642,980 is 1308344826180.
Find LCM of 230,422,857,642,980 with Prime Factorization
| 2 | 230, 422, 857, 642, 980 |
| 5 | 115, 211, 857, 321, 490 |
| 23, 211, 857, 321, 98 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 23 x 211 x 857 x 321 x 98 = 1308344826180
Therefore, the lowest common multiple of 230,422,857,642,980 is 1308344826180.
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.
230 x 422 x 857 x 642 x 980 = 52333793047200
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.
230 : 1, 2, 5, 10, 23, 46, 115, 230
422 : 1, 2, 211, 422
857 : 1, 857
642 : 1, 2, 3, 6, 107, 214, 321, 642
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 230,422,857,642,980, is 1.
Now, the common factors can be found like this.
230:2x 5x 23
422:2x 211
857:857
642:2x 3x 107
980:2x 2x 5x 7x 7
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 5 = 40
Therefore, the value for common factors is 40.
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 = 52333793047200/(1x40)
LCM = 52333793047200/40
LCM = 1308344826180
Thus, we can understand that the LCM of 230,422,857,642,980 is 1308344826180.
