Given numbers are 825,980,770,845
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 825,980,770,845 is 27327300.
Find LCM of 825,980,770,845 with Prime Factorization
| 2 | 825, 980, 770, 845 |
| 5 | 825, 490, 385, 845 |
| 7 | 165, 98, 77, 169 |
| 11 | 165, 14, 11, 169 |
| 15, 14, 1, 169 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 11 x 15 x 14 x 1 x 169 = 27327300
Therefore, the lowest common multiple of 825,980,770,845 is 27327300.
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.
825 x 980 x 770 x 845 = 526050525000
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.
825 : 1, 3, 5, 11, 15, 25, 33, 55, 75, 165, 275, 825
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
845 : 1, 5, 13, 65, 169, 845
5 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 825,980,770,845, is 5.
Now, the common factors can be found like this.
825:3x 5x 5x 11
980:2x 2x 5x 7x 7
770:2x 5x 7x 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.
2x 5x 5x 7x 11 = 3850
Therefore, the value for common factors is 3850.
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 = 526050525000/(5x3850)
LCM = 526050525000/19250
LCM = 27327300
Thus, we can understand that the LCM of 825,980,770,845 is 27327300.
