Given numbers are 889,286,840,242,284
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 889,286,840,242,284 is 11914342440.
Find LCM of 889,286,840,242,284 with Prime Factorization
| 2 | 889, 286, 840, 242, 284 |
| 2 | 889, 143, 420, 121, 142 |
| 7 | 889, 143, 210, 121, 71 |
| 11 | 127, 143, 30, 121, 71 |
| 127, 13, 30, 11, 71 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 11 x 127 x 13 x 30 x 11 x 71 = 11914342440
Therefore, the lowest common multiple of 889,286,840,242,284 is 11914342440.
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.
889 x 286 x 840 x 242 x 284 = 14678469886080
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.
889 : 1, 7, 127, 889
286 : 1, 2, 11, 13, 22, 26, 143, 286
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
242 : 1, 2, 11, 22, 121, 242
284 : 1, 2, 4, 71, 142, 284
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 889,286,840,242,284, is 1.
Now, the common factors can be found like this.
889:7x 127
286:2x 11x 13
840:2x 2x 2x 3x 5x 7
242:2x 11x 11
284:2x 2x 71
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 7x 11 = 1232
Therefore, the value for common factors is 1232.
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 = 14678469886080/(1x1232)
LCM = 14678469886080/1232
LCM = 11914342440
Thus, we can understand that the LCM of 889,286,840,242,284 is 11914342440.
