Given numbers are 624,731,476,530,991
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 624,731,476,530,991 is 838531795920.
Find LCM of 624,731,476,530,991 with Prime Factorization
| 2 | 624, 731, 476, 530, 991 |
| 2 | 312, 731, 238, 265, 991 |
| 17 | 156, 731, 119, 265, 991 |
| 156, 43, 7, 265, 991 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 17 x 156 x 43 x 7 x 265 x 991 = 838531795920
Therefore, the lowest common multiple of 624,731,476,530,991 is 838531795920.
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.
624 x 731 x 476 x 530 x 991 = 114040324245120
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.
624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624
731 : 1, 17, 43, 731
476 : 1, 2, 4, 7, 14, 17, 28, 34, 68, 119, 238, 476
530 : 1, 2, 5, 10, 53, 106, 265, 530
991 : 1, 991
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 624,731,476,530,991, is 1.
Now, the common factors can be found like this.
624:2x 2x 2x 2x 3x 13
731:17x 43
476:2x 2x 7x 17
530:2x 5x 53
991:991
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 17 = 136
Therefore, the value for common factors is 136.
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 = 114040324245120/(1x136)
LCM = 114040324245120/136
LCM = 838531795920
Thus, we can understand that the LCM of 624,731,476,530,991 is 838531795920.
