Given numbers are 676,687,152,247,715
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 676,687,152,247,715 is 970621080.
Find LCM of 676,687,152,247,715 with Prime Factorization
| 2 | 676, 687, 152, 247, 715 |
| 2 | 338, 687, 76, 247, 715 |
| 13 | 169, 687, 38, 247, 715 |
| 19 | 13, 687, 38, 19, 55 |
| 13, 687, 2, 1, 55 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 19 x 13 x 687 x 2 x 1 x 55 = 970621080
Therefore, the lowest common multiple of 676,687,152,247,715 is 970621080.
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.
676 x 687 x 152 x 247 x 715 = 12466657151520
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.
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
687 : 1, 3, 229, 687
152 : 1, 2, 4, 8, 19, 38, 76, 152
247 : 1, 13, 19, 247
715 : 1, 5, 11, 13, 55, 65, 143, 715
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 676,687,152,247,715, is 1.
Now, the common factors can be found like this.
676:2x 2x 13x 13
687:3x 229
152:2x 2x 2x 19
247:13x 19
715:5x 11x 13
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 13x 13x 19 = 12844
Therefore, the value for common factors is 12844.
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 = 12466657151520/(1x12844)
LCM = 12466657151520/12844
LCM = 970621080
Thus, we can understand that the LCM of 676,687,152,247,715 is 970621080.
