Find LCM of 427,141,996,287,644 with Prime Factorization
| 2 | 427, 141, 996, 287, 644 |
| 2 | 427, 141, 498, 287, 322 |
| 3 | 427, 141, 249, 287, 161 |
| 7 | 427, 47, 83, 287, 161 |
| 61, 47, 83, 41, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 61 x 47 x 83 x 41 x 23 = 18849366732
Therefore, the lowest common multiple of 427,141,996,287,644 is 18849366732.
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.
427 x 141 x 996 x 287 x 644 = 11083427638416
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.
427 : 1, 7, 61, 427
141 : 1, 3, 47, 141
996 : 1, 2, 3, 4, 6, 12, 83, 166, 249, 332, 498, 996
287 : 1, 7, 41, 287
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 427,141,996,287,644, is 1.
Now, the common factors can be found like this.
427:7x 61
141:3x 47
996:2x 2x 3x 83
287:7x 41
644:2x 2x 7x 23
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 3x 7x 7 = 588
Therefore, the value for common factors is 588.
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 = 11083427638416/(1x588)
LCM = 11083427638416/588
LCM = 18849366732
Thus, we can understand that the LCM of 427,141,996,287,644 is 18849366732.
