Given numbers are 255,380,983,806,220
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 255,380,983,806,220 is 84451043820.
Find LCM of 255,380,983,806,220 with Prime Factorization
| 2 | 255, 380, 983, 806, 220 |
| 2 | 255, 190, 983, 403, 110 |
| 5 | 255, 95, 983, 403, 55 |
| 51, 19, 983, 403, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 51 x 19 x 983 x 403 x 11 = 84451043820
Therefore, the lowest common multiple of 255,380,983,806,220 is 84451043820.
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.
255 x 380 x 983 x 806 x 220 = 16890208764000
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.
255 : 1, 3, 5, 15, 17, 51, 85, 255
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
983 : 1, 983
806 : 1, 2, 13, 26, 31, 62, 403, 806
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 255,380,983,806,220, is 1.
Now, the common factors can be found like this.
255:3x 5x 17
380:2x 2x 5x 19
983:983
806:2x 13x 31
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.
2x 2x 2x 5x 5 = 200
Therefore, the value for common factors is 200.
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 = 16890208764000/(1x200)
LCM = 16890208764000/200
LCM = 84451043820
Thus, we can understand that the LCM of 255,380,983,806,220 is 84451043820.
