Given numbers are 845,638,278,174,638
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 845,638,278,174,638 is 224808870.
Find LCM of 845,638,278,174,638 with Prime Factorization
| 2 | 845, 638, 278, 174, 638 |
| 11 | 845, 319, 139, 87, 319 |
| 29 | 845, 29, 139, 87, 29 |
| 845, 1, 139, 3, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 29 x 845 x 1 x 139 x 3 x 1 = 224808870
Therefore, the lowest common multiple of 845,638,278,174,638 is 224808870.
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.
845 x 638 x 278 x 174 x 638 = 16637654850960
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.
845 : 1, 5, 13, 65, 169, 845
638 : 1, 2, 11, 22, 29, 58, 319, 638
278 : 1, 2, 139, 278
174 : 1, 2, 3, 6, 29, 58, 87, 174
638 : 1, 2, 11, 22, 29, 58, 319, 638
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 845,638,278,174,638, is 1.
Now, the common factors can be found like this.
845:5x 13x 13
638:2x 11x 29
278:2x 139
174:2x 3x 29
638:2x 11x 29
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 11x 29x 29 = 74008
Therefore, the value for common factors is 74008.
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 = 16637654850960/(1x74008)
LCM = 16637654850960/74008
LCM = 224808870
Thus, we can understand that the LCM of 845,638,278,174,638 is 224808870.
