Find LCM of 826,245,643,168,969 with Prime Factorization
| 2 | 826, 245, 643, 168, 969 |
| 3 | 413, 245, 643, 84, 969 |
| 7 | 413, 245, 643, 28, 323 |
| 59, 35, 643, 4, 323 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 59 x 35 x 643 x 4 x 323 = 72051467880
Therefore, the lowest common multiple of 826,245,643,168,969 is 72051467880.
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.
826 x 245 x 643 x 168 x 969 = 21183131556720
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.
826 : 1, 2, 7, 14, 59, 118, 413, 826
245 : 1, 5, 7, 35, 49, 245
643 : 1, 643
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
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 826,245,643,168,969, is 1.
Now, the common factors can be found like this.
826:2x 7x 59
245:5x 7x 7
643:643
168:2x 2x 2x 3x 7
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 3x 7x 7 = 294
Therefore, the value for common factors is 294.
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 = 21183131556720/(1x294)
LCM = 21183131556720/294
LCM = 72051467880
Thus, we can understand that the LCM of 826,245,643,168,969 is 72051467880.
