Given numbers are 979,980,859,786,819
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 979,980,859,786,819 is 12631621062060.
Find LCM of 979,980,859,786,819 with Prime Factorization
| 2 | 979, 980, 859, 786, 819 |
| 3 | 979, 490, 859, 393, 819 |
| 7 | 979, 490, 859, 131, 273 |
| 979, 70, 859, 131, 39 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 979 x 70 x 859 x 131 x 39 = 12631621062060
Therefore, the lowest common multiple of 979,980,859,786,819 is 12631621062060.
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.
979 x 980 x 859 x 786 x 819 = 530528084606520
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.
979 : 1, 11, 89, 979
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
859 : 1, 859
786 : 1, 2, 3, 6, 131, 262, 393, 786
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 979,980,859,786,819, is 1.
Now, the common factors can be found like this.
979:11x 89
980:2x 2x 5x 7x 7
859:859
786:2x 3x 131
819:3x 3x 7x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 7 = 42
Therefore, the value for common factors is 42.
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 = 530528084606520/(1x42)
LCM = 530528084606520/42
LCM = 12631621062060
Thus, we can understand that the LCM of 979,980,859,786,819 is 12631621062060.
