Given numbers are 348,720,771,905
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 348,720,771,905 is 971274960.
Find LCM of 348,720,771,905 with Prime Factorization
| 2 | 348, 720, 771, 905 |
| 2 | 174, 360, 771, 905 |
| 3 | 87, 180, 771, 905 |
| 5 | 29, 60, 257, 905 |
| 29, 12, 257, 181 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 29 x 12 x 257 x 181 = 971274960
Therefore, the lowest common multiple of 348,720,771,905 is 971274960.
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.
348 x 720 x 771 x 905 = 174829492800
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.
348 : 1, 2, 3, 4, 6, 12, 29, 58, 87, 116, 174, 348
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
771 : 1, 3, 257, 771
905 : 1, 5, 181, 905
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 348,720,771,905, is 1.
Now, the common factors can be found like this.
348:2x 2x 3x 29
720:2x 2x 2x 2x 3x 3x 5
771:3x 257
905:5x 181
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 5 = 180
Therefore, the value for common factors is 180.
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 = 174829492800/(1x180)
LCM = 174829492800/180
LCM = 971274960
Thus, we can understand that the LCM of 348,720,771,905 is 971274960.
