Given numbers are 969,442,462,128,943
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 969,442,462,128,943 is 117079138176.
Find LCM of 969,442,462,128,943 with Prime Factorization
| 2 | 969, 442, 462, 128, 943 |
| 3 | 969, 221, 231, 64, 943 |
| 17 | 323, 221, 77, 64, 943 |
| 19, 13, 77, 64, 943 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 19 x 13 x 77 x 64 x 943 = 117079138176
Therefore, the lowest common multiple of 969,442,462,128,943 is 117079138176.
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.
969 x 442 x 462 x 128 x 943 = 23884144187904
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.
969 : 1, 3, 17, 19, 51, 57, 323, 969
442 : 1, 2, 13, 17, 26, 34, 221, 442
462 : 1, 2, 3, 6, 7, 11, 14, 21, 22, 33, 42, 66, 77, 154, 231, 462
128 : 1, 2, 4, 8, 16, 32, 64, 128
943 : 1, 23, 41, 943
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 969,442,462,128,943, is 1.
Now, the common factors can be found like this.
969:3x 17x 19
442:2x 13x 17
462:2x 3x 7x 11
128:2x 2x 2x 2x 2x 2x 2
943:23x 41
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 17 = 204
Therefore, the value for common factors is 204.
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 = 23884144187904/(1x204)
LCM = 23884144187904/204
LCM = 117079138176
Thus, we can understand that the LCM of 969,442,462,128,943 is 117079138176.
