The LCM of 392,578,763,477,753 is 1478435928984.
Find LCM of 392,578,763,477,753 with Prime Factorization
| 2 | 392, 578, 763, 477, 753 |
| 3 | 196, 289, 763, 477, 753 |
| 7 | 196, 289, 763, 159, 251 |
| 28, 289, 109, 159, 251 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 28 x 289 x 109 x 159 x 251 = 1478435928984
Therefore, the lowest common multiple of 392,578,763,477,753 is 1478435928984.
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.
392 x 578 x 763 x 477 x 753 = 62094309017328
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.
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
578 : 1, 2, 17, 34, 289, 578
763 : 1, 7, 109, 763
477 : 1, 3, 9, 53, 159, 477
753 : 1, 3, 251, 753
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 392,578,763,477,753, is 1.
Now, the common factors can be found like this.
392:2x 2x 2x 7x 7
578:2x 17x 17
763:7x 109
477:3x 3x 53
753:3x 251
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 7 = 42
Therefore, the value for common factors is 42.
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 = 62094309017328/(1x42)
LCM = 62094309017328/42
LCM = 1478435928984
Thus, we can understand that the LCM of 392,578,763,477,753 is 1478435928984.
