Given numbers are 379,338,780,256,278
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 379,338,780,256,278 is 34187861760.
Find LCM of 379,338,780,256,278 with Prime Factorization
| 2 | 379, 338, 780, 256, 278 |
| 2 | 379, 169, 390, 128, 139 |
| 13 | 379, 169, 195, 64, 139 |
| 379, 13, 15, 64, 139 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 379 x 13 x 15 x 64 x 139 = 34187861760
Therefore, the lowest common multiple of 379,338,780,256,278 is 34187861760.
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 338 x 780 x 256 x 278 = 7111075246080
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
338 : 1, 2, 13, 26, 169, 338
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
256 : 1, 2, 4, 8, 16, 32, 64, 128, 256
278 : 1, 2, 139, 278
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 379,338,780,256,278, is 1.
Now, the common factors can be found like this.
379:379
338:2x 13x 13
780:2x 2x 3x 5x 13
256:2x 2x 2x 2x 2x 2x 2x 2
278:2x 139
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 13 = 208
Therefore, the value for common factors is 208.
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 = 7111075246080/(1x208)
LCM = 7111075246080/208
LCM = 34187861760
Thus, we can understand that the LCM of 379,338,780,256,278 is 34187861760.
