Given numbers are 309,627,924,868
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 309,627,924,868 is 56056308.
Find LCM of 309,627,924,868 with Prime Factorization
| 2 | 309, 627, 924, 868 |
| 2 | 309, 627, 462, 434 |
| 3 | 309, 627, 231, 217 |
| 7 | 103, 209, 77, 217 |
| 11 | 103, 209, 11, 31 |
| 103, 19, 1, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 11 x 103 x 19 x 1 x 31 = 56056308
Therefore, the lowest common multiple of 309,627,924,868 is 56056308.
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.
309 x 627 x 924 x 868 = 155388085776
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.
309 : 1, 3, 103, 309
627 : 1, 3, 11, 19, 33, 57, 209, 627
924 : 1, 2, 3, 4, 6, 7, 11, 12, 14, 21, 22, 28, 33, 42, 44, 66, 77, 84, 132, 154, 231, 308, 462, 924
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 309,627,924,868, is 1.
Now, the common factors can be found like this.
309:3x 103
627:3x 11x 19
924:2x 2x 3x 7x 11
868:2x 2x 7x 31
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 3x 7x 11 = 2772
Therefore, the value for common factors is 2772.
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 = 155388085776/(1x2772)
LCM = 155388085776/2772
LCM = 56056308
Thus, we can understand that the LCM of 309,627,924,868 is 56056308.
