Given numbers are 247,476,169,820
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 247,476,169,820 is 313329380.
Find LCM of 247,476,169,820 with Prime Factorization
| 2 | 247, 476, 169, 820 |
| 2 | 247, 238, 169, 410 |
| 13 | 247, 119, 169, 205 |
| 19, 119, 13, 205 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 19 x 119 x 13 x 205 = 313329380
Therefore, the lowest common multiple of 247,476,169,820 is 313329380.
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.
247 x 476 x 169 x 820 = 16293127760
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.
247 : 1, 13, 19, 247
476 : 1, 2, 4, 7, 14, 17, 28, 34, 68, 119, 238, 476
169 : 1, 13, 169
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 247,476,169,820, is 1.
Now, the common factors can be found like this.
247:13x 19
476:2x 2x 7x 17
169:13x 13
820:2x 2x 5x 41
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 13 = 52
Therefore, the value for common factors is 52.
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 = 16293127760/(1x52)
LCM = 16293127760/52
LCM = 313329380
Thus, we can understand that the LCM of 247,476,169,820 is 313329380.
