Given numbers are 447,628,447,645,936
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 447,628,447,645,936 is 4707607320.
Find LCM of 447,628,447,645,936 with Prime Factorization
| 2 | 447, 628, 447, 645, 936 |
| 2 | 447, 314, 447, 645, 468 |
| 3 | 447, 157, 447, 645, 234 |
| 149 | 149, 157, 149, 215, 78 |
| 1, 157, 1, 215, 78 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 149 x 1 x 157 x 1 x 215 x 78 = 4707607320
Therefore, the lowest common multiple of 447,628,447,645,936 is 4707607320.
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.
447 x 628 x 447 x 645 x 936 = 75754816993440
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.
447 : 1, 3, 149, 447
628 : 1, 2, 4, 157, 314, 628
447 : 1, 3, 149, 447
645 : 1, 3, 5, 15, 43, 129, 215, 645
936 : 1, 2, 3, 4, 6, 8, 9, 12, 13, 18, 24, 26, 36, 39, 52, 72, 78, 104, 117, 156, 234, 312, 468, 936
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 447,628,447,645,936, is 1.
Now, the common factors can be found like this.
447:3x 149
628:2x 2x 157
447:3x 149
645:3x 5x 43
936:2x 2x 2x 3x 3x 13
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 3x 3x 149 = 16092
Therefore, the value for common factors is 16092.
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 = 75754816993440/(1x16092)
LCM = 75754816993440/16092
LCM = 4707607320
Thus, we can understand that the LCM of 447,628,447,645,936 is 4707607320.
