Given numbers are 716,920,880,397
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 716,920,880,397 is 1438315120.
Find LCM of 716,920,880,397 with Prime Factorization
| 2 | 716, 920, 880, 397 |
| 2 | 358, 460, 440, 397 |
| 2 | 179, 230, 220, 397 |
| 5 | 179, 115, 110, 397 |
| 179, 23, 22, 397 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 179 x 23 x 22 x 397 = 1438315120
Therefore, the lowest common multiple of 716,920,880,397 is 1438315120.
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.
716 x 920 x 880 x 397 = 230130419200
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.
716 : 1, 2, 4, 179, 358, 716
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880
397 : 1, 397
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 716,920,880,397, is 1.
Now, the common factors can be found like this.
716:2x 2x 179
920:2x 2x 2x 5x 23
880:2x 2x 2x 2x 5x 11
397:397
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 2x 2x 5 = 160
Therefore, the value for common factors is 160.
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 = 230130419200/(1x160)
LCM = 230130419200/160
LCM = 1438315120
Thus, we can understand that the LCM of 716,920,880,397 is 1438315120.
