Given numbers are 361,878,697,380
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 361,878,697,380 is 2209197260.
Find LCM of 361,878,697,380 with Prime Factorization
| 2 | 361, 878, 697, 380 |
| 19 | 361, 439, 697, 190 |
| 19, 439, 697, 10 |
Multiply the prime numbers at the bottom and the left side.
2 x 19 x 19 x 439 x 697 x 10 = 2209197260
Therefore, the lowest common multiple of 361,878,697,380 is 2209197260.
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.
361 x 878 x 697 x 380 = 83949495880
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.
361 : 1, 19, 361
878 : 1, 2, 439, 878
697 : 1, 17, 41, 697
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 361,878,697,380, is 1.
Now, the common factors can be found like this.
361:19x 19
878:2x 439
697:17x 41
380:2x 2x 5x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 19 = 38
Therefore, the value for common factors is 38.
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 = 83949495880/(1x38)
LCM = 83949495880/38
LCM = 2209197260
Thus, we can understand that the LCM of 361,878,697,380 is 2209197260.
