Given numbers are 278,778,278,778,257
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 278,778,278,778,257 is 27792494.
Find LCM of 278,778,278,778,257 with Prime Factorization
| 2 | 278, 778, 278, 778, 257 |
| 139 | 139, 389, 139, 389, 257 |
| 389 | 1, 389, 1, 389, 257 |
| 1, 1, 1, 1, 257 |
Multiply the prime numbers at the bottom and the left side.
2 x 139 x 389 x 1 x 1 x 1 x 1 x 257 = 27792494
Therefore, the lowest common multiple of 278,778,278,778,257 is 27792494.
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.
278 x 778 x 278 x 778 x 257 = 12022143544592
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.
278 : 1, 2, 139, 278
778 : 1, 2, 389, 778
278 : 1, 2, 139, 278
778 : 1, 2, 389, 778
257 : 1, 257
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 278,778,278,778,257, is 1.
Now, the common factors can be found like this.
278:2x 139
778:2x 389
278:2x 139
778:2x 389
257:257
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 139x 389 = 432568
Therefore, the value for common factors is 432568.
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 = 12022143544592/(1x432568)
LCM = 12022143544592/432568
LCM = 27792494
Thus, we can understand that the LCM of 278,778,278,778,257 is 27792494.
