Given numbers are 860,543,697,861,979
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 860,543,697,861,979 is 2230549116180.
Find LCM of 860,543,697,861,979 with Prime Factorization
| 3 | 860, 543, 697, 861, 979 |
| 41 | 860, 181, 697, 287, 979 |
| 860, 181, 17, 7, 979 |
Multiply the prime numbers at the bottom and the left side.
3 x 41 x 860 x 181 x 17 x 7 x 979 = 2230549116180
Therefore, the lowest common multiple of 860,543,697,861,979 is 2230549116180.
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 543 x 697 x 861 x 979 = 274357541290140
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
543 : 1, 3, 181, 543
697 : 1, 17, 41, 697
861 : 1, 3, 7, 21, 41, 123, 287, 861
979 : 1, 11, 89, 979
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 860,543,697,861,979, is 1.
Now, the common factors can be found like this.
860:2x 2x 5x 43
543:3x 181
697:17x 41
861:3x 7x 41
979:11x 89
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 41 = 123
Therefore, the value for common factors is 123.
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 = 274357541290140/(1x123)
LCM = 274357541290140/123
LCM = 2230549116180
Thus, we can understand that the LCM of 860,543,697,861,979 is 2230549116180.
