Given numbers are 379,988,611,780
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 379,988,611,780 is 263988660.
Find LCM of 379,988,611,780 with Prime Factorization
| 2 | 379, 988, 611, 780 |
| 2 | 379, 494, 611, 390 |
| 13 | 379, 247, 611, 195 |
| 379, 19, 47, 15 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 379 x 19 x 47 x 15 = 263988660
Therefore, the lowest common multiple of 379,988,611,780 is 263988660.
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.
379 x 988 x 611 x 780 = 178456334160
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.
379 : 1, 379
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
611 : 1, 13, 47, 611
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 379,988,611,780, is 1.
Now, the common factors can be found like this.
379:379
988:2x 2x 13x 19
611:13x 47
780:2x 2x 3x 5x 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 13 = 676
Therefore, the value for common factors is 676.
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 = 178456334160/(1x676)
LCM = 178456334160/676
LCM = 263988660
Thus, we can understand that the LCM of 379,988,611,780 is 263988660.
