Find LCM of 754,168,957,781,309 with Prime Factorization
| 2 | 754, 168, 957, 781, 309 |
| 3 | 377, 84, 957, 781, 309 |
| 11 | 377, 28, 319, 781, 103 |
| 29 | 377, 28, 29, 71, 103 |
| 13, 28, 1, 71, 103 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 29 x 13 x 28 x 1 x 71 x 103 = 5094937848
Therefore, the lowest common multiple of 754,168,957,781,309 is 5094937848.
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.
754 x 168 x 957 x 781 x 309 = 29255133123216
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.
754 : 1, 2, 13, 26, 29, 58, 377, 754
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
957 : 1, 3, 11, 29, 33, 87, 319, 957
781 : 1, 11, 71, 781
309 : 1, 3, 103, 309
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 754,168,957,781,309, is 1.
Now, the common factors can be found like this.
754:2x 13x 29
168:2x 2x 2x 3x 7
957:3x 11x 29
781:11x 71
309:3x 103
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 11x 29 = 5742
Therefore, the value for common factors is 5742.
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 = 29255133123216/(1x5742)
LCM = 29255133123216/5742
LCM = 5094937848
Thus, we can understand that the LCM of 754,168,957,781,309 is 5094937848.
