Find LCM of 249,866,380,102,720 with Prime Factorization
| 2 | 249, 866, 380, 102, 720 |
| 2 | 249, 433, 190, 51, 360 |
| 3 | 249, 433, 95, 51, 180 |
| 5 | 83, 433, 95, 17, 60 |
| 83, 433, 19, 17, 12 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 83 x 433 x 19 x 17 x 12 = 8357973840
Therefore, the lowest common multiple of 249,866,380,102,720 is 8357973840.
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.
249 x 866 x 380 x 102 x 720 = 6017741164800
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.
249 : 1, 3, 83, 249
866 : 1, 2, 433, 866
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
102 : 1, 2, 3, 6, 17, 34, 51, 102
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 249,866,380,102,720, is 1.
Now, the common factors can be found like this.
249:3x 83
866:2x 433
380:2x 2x 5x 19
102:2x 3x 17
720:2x 2x 2x 2x 3x 3x 5
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 2x 3x 3x 5 = 720
Therefore, the value for common factors is 720.
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 = 6017741164800/(1x720)
LCM = 6017741164800/720
LCM = 8357973840
Thus, we can understand that the LCM of 249,866,380,102,720 is 8357973840.
