Given numbers are 860,215,278,715,139
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 860,215,278,715,139 is 17094220.
Find LCM of 860,215,278,715,139 with Prime Factorization
| 2 | 860, 215, 278, 715, 139 |
| 5 | 430, 215, 139, 715, 139 |
| 43 | 86, 43, 139, 143, 139 |
| 139 | 2, 1, 139, 143, 139 |
| 2, 1, 1, 143, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 43 x 139 x 2 x 1 x 1 x 143 x 1 = 17094220
Therefore, the lowest common multiple of 860,215,278,715,139 is 17094220.
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.
860 x 215 x 278 x 715 x 139 = 5108607647000
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.
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
215 : 1, 5, 43, 215
278 : 1, 2, 139, 278
715 : 1, 5, 11, 13, 55, 65, 143, 715
139 : 1, 139
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 860,215,278,715,139, is 1.
Now, the common factors can be found like this.
860:2x 2x 5x 43
215:5x 43
278:2x 139
715:5x 11x 13
139:139
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 5x 43x 139 = 298850
Therefore, the value for common factors is 298850.
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 = 5108607647000/(1x298850)
LCM = 5108607647000/298850
LCM = 17094220
Thus, we can understand that the LCM of 860,215,278,715,139 is 17094220.
