Given numbers are 915,172,969,810,965
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 915,172,969,810,965 is 264894619140.
Find LCM of 915,172,969,810,965 with Prime Factorization
| 2 | 915, 172, 969, 810, 965 |
| 3 | 915, 86, 969, 405, 965 |
| 5 | 305, 86, 323, 135, 965 |
| 61, 86, 323, 27, 193 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 61 x 86 x 323 x 27 x 193 = 264894619140
Therefore, the lowest common multiple of 915,172,969,810,965 is 264894619140.
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 172 x 969 x 810 x 965 = 119202578613000
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
172 : 1, 2, 4, 43, 86, 172
969 : 1, 3, 17, 19, 51, 57, 323, 969
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
965 : 1, 5, 193, 965
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 915,172,969,810,965, is 1.
Now, the common factors can be found like this.
915:3x 5x 61
172:2x 2x 43
969:3x 17x 19
810:2x 3x 3x 3x 3x 5
965:5x 193
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 5x 5 = 450
Therefore, the value for common factors is 450.
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 = 119202578613000/(1x450)
LCM = 119202578613000/450
LCM = 264894619140
Thus, we can understand that the LCM of 915,172,969,810,965 is 264894619140.
