Given numbers are 915,966,989,814,836
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 915,966,989,814,836 is 195940145940.
Find LCM of 915,966,989,814,836 with Prime Factorization
| 2 | 915, 966, 989, 814, 836 |
| 3 | 915, 483, 989, 407, 418 |
| 11 | 305, 161, 989, 407, 418 |
| 23 | 305, 161, 989, 37, 38 |
| 305, 7, 43, 37, 38 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 23 x 305 x 7 x 43 x 37 x 38 = 195940145940
Therefore, the lowest common multiple of 915,966,989,814,836 is 195940145940.
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.
915 x 966 x 989 x 814 x 836 = 594874283073840
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.
915 : 1, 3, 5, 15, 61, 183, 305, 915
966 : 1, 2, 3, 6, 7, 14, 21, 23, 42, 46, 69, 138, 161, 322, 483, 966
989 : 1, 23, 43, 989
814 : 1, 2, 11, 22, 37, 74, 407, 814
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 915,966,989,814,836, is 1.
Now, the common factors can be found like this.
915:3x 5x 61
966:2x 3x 7x 23
989:23x 43
814:2x 11x 37
836:2x 2x 11x 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 3x 11x 23 = 3036
Therefore, the value for common factors is 3036.
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 = 594874283073840/(1x3036)
LCM = 594874283073840/3036
LCM = 195940145940
Thus, we can understand that the LCM of 915,966,989,814,836 is 195940145940.
