Given numbers are 628,772,917,489,912
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 628,772,917,489,912 is 4130558143152.
Find LCM of 628,772,917,489,912 with Prime Factorization
| 2 | 628, 772, 917, 489, 912 |
| 2 | 314, 386, 917, 489, 456 |
| 3 | 157, 193, 917, 489, 228 |
| 157, 193, 917, 163, 76 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 157 x 193 x 917 x 163 x 76 = 4130558143152
Therefore, the lowest common multiple of 628,772,917,489,912 is 4130558143152.
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.
628 x 772 x 917 x 489 x 912 = 198266790871296
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.
628 : 1, 2, 4, 157, 314, 628
772 : 1, 2, 4, 193, 386, 772
917 : 1, 7, 131, 917
489 : 1, 3, 163, 489
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 628,772,917,489,912, is 1.
Now, the common factors can be found like this.
628:2x 2x 157
772:2x 2x 193
917:7x 131
489:3x 163
912:2x 2x 2x 2x 3x 19
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 3 = 48
Therefore, the value for common factors is 48.
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 = 198266790871296/(1x48)
LCM = 198266790871296/48
LCM = 4130558143152
Thus, we can understand that the LCM of 628,772,917,489,912 is 4130558143152.
