Given numbers are 979,429,462,993
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 979,429,462,993 is 176930754.
Find LCM of 979,429,462,993 with Prime Factorization
| 3 | 979, 429, 462, 993 |
| 11 | 979, 143, 154, 331 |
| 89, 13, 14, 331 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 89 x 13 x 14 x 331 = 176930754
Therefore, the lowest common multiple of 979,429,462,993 is 176930754.
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 429 x 462 x 993 = 192677591106
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
429 : 1, 3, 11, 13, 33, 39, 143, 429
462 : 1, 2, 3, 6, 7, 11, 14, 21, 22, 33, 42, 66, 77, 154, 231, 462
993 : 1, 3, 331, 993
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 979,429,462,993, is 1.
Now, the common factors can be found like this.
979:11x 89
429:3x 11x 13
462:2x 3x 7x 11
993:3x 331
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 11x 11 = 1089
Therefore, the value for common factors is 1089.
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 = 192677591106/(1x1089)
LCM = 192677591106/1089
LCM = 176930754
Thus, we can understand that the LCM of 979,429,462,993 is 176930754.
