Given numbers are 380,866,451,860,278
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 380,866,451,860,278 is 443538466580.
Find LCM of 380,866,451,860,278 with Prime Factorization
| 2 | 380, 866, 451, 860, 278 |
| 2 | 190, 433, 451, 430, 139 |
| 5 | 95, 433, 451, 215, 139 |
| 19, 433, 451, 43, 139 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 19 x 433 x 451 x 43 x 139 = 443538466580
Therefore, the lowest common multiple of 380,866,451,860,278 is 443538466580.
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.
380 x 866 x 451 x 860 x 278 = 35483077326400
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.
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
866 : 1, 2, 433, 866
451 : 1, 11, 41, 451
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
278 : 1, 2, 139, 278
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 380,866,451,860,278, is 1.
Now, the common factors can be found like this.
380:2x 2x 5x 19
866:2x 433
451:11x 41
860:2x 2x 5x 43
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 5 = 80
Therefore, the value for common factors is 80.
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 = 35483077326400/(1x80)
LCM = 35483077326400/80
LCM = 443538466580
Thus, we can understand that the LCM of 380,866,451,860,278 is 443538466580.
