The LCM of 228,660,847,667 is 644041860.
Find LCM of 228,660,847,667 with Prime Factorization
| 2 | 228, 660, 847, 667 |
| 2 | 114, 330, 847, 667 |
| 3 | 57, 165, 847, 667 |
| 11 | 19, 55, 847, 667 |
| 19, 5, 77, 667 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 19 x 5 x 77 x 667 = 644041860
Therefore, the lowest common multiple of 228,660,847,667 is 644041860.
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.
228 x 660 x 847 x 667 = 85013525520
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.
228 : 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, 228
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
847 : 1, 7, 11, 77, 121, 847
667 : 1, 23, 29, 667
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 228,660,847,667, is 1.
Now, the common factors can be found like this.
228:2x 2x 3x 19
660:2x 2x 3x 5x 11
847:7x 11x 11
667:23x 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 3x 11 = 132
Therefore, the value for common factors is 132.
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 = 85013525520/(1x132)
LCM = 85013525520/132
LCM = 644041860
Thus, we can understand that the LCM of 228,660,847,667 is 644041860.
