Given numbers are 767,315,990,845
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 767,315,990,845 is 69099030.
Find LCM of 767,315,990,845 with Prime Factorization
| 3 | 767, 315, 990, 845 |
| 3 | 767, 105, 330, 845 |
| 5 | 767, 35, 110, 845 |
| 13 | 767, 7, 22, 169 |
| 59, 7, 22, 13 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 13 x 59 x 7 x 22 x 13 = 69099030
Therefore, the lowest common multiple of 767,315,990,845 is 69099030.
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.
767 x 315 x 990 x 845 = 202114662750
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.
767 : 1, 13, 59, 767
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
845 : 1, 5, 13, 65, 169, 845
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 767,315,990,845, is 1.
Now, the common factors can be found like this.
767:13x 59
315:3x 3x 5x 7
990:2x 3x 3x 5x 11
845:5x 13x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5x 5x 13 = 2925
Therefore, the value for common factors is 2925.
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 = 202114662750/(1x2925)
LCM = 202114662750/2925
LCM = 69099030
Thus, we can understand that the LCM of 767,315,990,845 is 69099030.
