Given numbers are 484,147,364,840
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 484,147,364,840 is 9249240.
Find LCM of 484,147,364,840 with Prime Factorization
| 2 | 484, 147, 364, 840 |
| 2 | 242, 147, 182, 420 |
| 3 | 121, 147, 91, 210 |
| 7 | 121, 49, 91, 70 |
| 121, 7, 13, 10 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 121 x 7 x 13 x 10 = 9249240
Therefore, the lowest common multiple of 484,147,364,840 is 9249240.
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.
484 x 147 x 364 x 840 = 21754212480
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.
484 : 1, 2, 4, 11, 22, 44, 121, 242, 484
147 : 1, 3, 7, 21, 49, 147
364 : 1, 2, 4, 7, 13, 14, 26, 28, 52, 91, 182, 364
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
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 484,147,364,840, is 1.
Now, the common factors can be found like this.
484:2x 2x 11x 11
147:3x 7x 7
364:2x 2x 7x 13
840:2x 2x 2x 3x 5x 7
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 7x 7 = 2352
Therefore, the value for common factors is 2352.
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 = 21754212480/(1x2352)
LCM = 21754212480/2352
LCM = 9249240
Thus, we can understand that the LCM of 484,147,364,840 is 9249240.
