Find LCM of 558,164,620,969,969 with Prime Factorization
| 2 | 558, 164, 620, 969, 969 |
| 2 | 279, 82, 310, 969, 969 |
| 3 | 279, 41, 155, 969, 969 |
| 17 | 93, 41, 155, 323, 323 |
| 19 | 93, 41, 155, 19, 19 |
| 31 | 93, 41, 155, 1, 1 |
| 3, 41, 5, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 17 x 19 x 31 x 3 x 41 x 5 x 1 x 1 = 73895940
Therefore, the lowest common multiple of 558,164,620,969,969 is 73895940.
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.
558 x 164 x 620 x 969 x 969 = 53274243399840
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.
558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558
164 : 1, 2, 4, 41, 82, 164
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
969 : 1, 3, 17, 19, 51, 57, 323, 969
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 558,164,620,969,969, is 1.
Now, the common factors can be found like this.
558:2x 3x 3x 31
164:2x 2x 41
620:2x 2x 5x 31
969:3x 17x 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 3x 17x 19x 31 = 720936
Therefore, the value for common factors is 720936.
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 = 53274243399840/(1x720936)
LCM = 53274243399840/720936
LCM = 73895940
Thus, we can understand that the LCM of 558,164,620,969,969 is 73895940.
