Given numbers are 171,480,838,669,724
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 171,480,838,669,724 is 462714973920.
Find LCM of 171,480,838,669,724 with Prime Factorization
| 2 | 171, 480, 838, 669, 724 |
| 2 | 171, 240, 419, 669, 362 |
| 3 | 171, 120, 419, 669, 181 |
| 57, 40, 419, 223, 181 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 57 x 40 x 419 x 223 x 181 = 462714973920
Therefore, the lowest common multiple of 171,480,838,669,724 is 462714973920.
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.
171 x 480 x 838 x 669 x 724 = 33315478122240
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.
171 : 1, 3, 9, 19, 57, 171
480 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 80, 96, 120, 160, 240, 480
838 : 1, 2, 419, 838
669 : 1, 3, 223, 669
724 : 1, 2, 4, 181, 362, 724
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 171,480,838,669,724, is 1.
Now, the common factors can be found like this.
171:3x 3x 19
480:2x 2x 2x 2x 2x 3x 5
838:2x 419
669:3x 223
724:2x 2x 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 2x 3x 3 = 72
Therefore, the value for common factors is 72.
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 = 33315478122240/(1x72)
LCM = 33315478122240/72
LCM = 462714973920
Thus, we can understand that the LCM of 171,480,838,669,724 is 462714973920.
