Given numbers are 669,979,923,286
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 669,979,923,286 is 1209039546.
Find LCM of 669,979,923,286 with Prime Factorization
| 11 | 669, 979, 923, 286 |
| 13 | 669, 89, 923, 26 |
| 669, 89, 71, 2 |
Multiply the prime numbers at the bottom and the left side.
11 x 13 x 669 x 89 x 71 x 2 = 1209039546
Therefore, the lowest common multiple of 669,979,923,286 is 1209039546.
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.
669 x 979 x 923 x 286 = 172892655078
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.
669 : 1, 3, 223, 669
979 : 1, 11, 89, 979
923 : 1, 13, 71, 923
286 : 1, 2, 11, 13, 22, 26, 143, 286
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 669,979,923,286, is 1.
Now, the common factors can be found like this.
669:3x 223
979:11x 89
923:13x 71
286:2x 11x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 13 = 143
Therefore, the value for common factors is 143.
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 = 172892655078/(1x143)
LCM = 172892655078/143
LCM = 1209039546
Thus, we can understand that the LCM of 669,979,923,286 is 1209039546.
