Find LCM of 163,976,840,247,969 with Prime Factorization
| 2 | 163, 976, 840, 247, 969 |
| 2 | 163, 488, 420, 247, 969 |
| 2 | 163, 244, 210, 247, 969 |
| 3 | 163, 122, 105, 247, 969 |
| 19 | 163, 122, 35, 247, 323 |
| 163, 122, 35, 13, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 19 x 163 x 122 x 35 x 13 x 17 = 70141103760
Therefore, the lowest common multiple of 163,976,840,247,969 is 70141103760.
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.
163 x 976 x 840 x 247 x 969 = 31984343314560
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.
163 : 1, 163
976 : 1, 2, 4, 8, 16, 61, 122, 244, 488, 976
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
247 : 1, 13, 19, 247
969 : 1, 3, 17, 19, 51, 57, 323, 969
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 163,976,840,247,969, is 1.
Now, the common factors can be found like this.
163:163
976:2x 2x 2x 2x 61
840:2x 2x 2x 3x 5x 7
247:13x 19
969:3x 17x 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 2x 3x 19 = 456
Therefore, the value for common factors is 456.
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 = 31984343314560/(1x456)
LCM = 31984343314560/456
LCM = 70141103760
Thus, we can understand that the LCM of 163,976,840,247,969 is 70141103760.
