Given numbers are 662,454,868,315
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 662,454,868,315 is 2934851220.
Find LCM of 662,454,868,315 with Prime Factorization
| 2 | 662, 454, 868, 315 |
| 7 | 331, 227, 434, 315 |
| 331, 227, 62, 45 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 331 x 227 x 62 x 45 = 2934851220
Therefore, the lowest common multiple of 662,454,868,315 is 2934851220.
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.
662 x 454 x 868 x 315 = 82175834160
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.
662 : 1, 2, 331, 662
454 : 1, 2, 227, 454
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 662,454,868,315, is 1.
Now, the common factors can be found like this.
662:2x 331
454:2x 227
868:2x 2x 7x 31
315:3x 3x 5x 7
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 7 = 28
Therefore, the value for common factors is 28.
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 = 82175834160/(1x28)
LCM = 82175834160/28
LCM = 2934851220
Thus, we can understand that the LCM of 662,454,868,315 is 2934851220.
