Given numbers are 385,633,857,153,220
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 385,633,857,153,220 is 42606457740.
Find LCM of 385,633,857,153,220 with Prime Factorization
| 3 | 385, 633, 857, 153, 220 |
| 5 | 385, 211, 857, 51, 220 |
| 11 | 77, 211, 857, 51, 44 |
| 7, 211, 857, 51, 4 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 11 x 7 x 211 x 857 x 51 x 4 = 42606457740
Therefore, the lowest common multiple of 385,633,857,153,220 is 42606457740.
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.
385 x 633 x 857 x 153 x 220 = 7030065527100
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.
385 : 1, 5, 7, 11, 35, 55, 77, 385
633 : 1, 3, 211, 633
857 : 1, 857
153 : 1, 3, 9, 17, 51, 153
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 385,633,857,153,220, is 1.
Now, the common factors can be found like this.
385:5x 7x 11
633:3x 211
857:857
153:3x 3x 17
220:2x 2x 5x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 11 = 165
Therefore, the value for common factors is 165.
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 = 7030065527100/(1x165)
LCM = 7030065527100/165
LCM = 42606457740
Thus, we can understand that the LCM of 385,633,857,153,220 is 42606457740.
