Given numbers are 942,979,921,445
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 942,979,921,445 is 1415604630.
Find LCM of 942,979,921,445 with Prime Factorization
| 3 | 942, 979, 921, 445 |
| 89 | 314, 979, 307, 445 |
| 314, 11, 307, 5 |
Multiply the prime numbers at the bottom and the left side.
3 x 89 x 314 x 11 x 307 x 5 = 1415604630
Therefore, the lowest common multiple of 942,979,921,445 is 1415604630.
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.
942 x 979 x 921 x 445 = 377966436210
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.
942 : 1, 2, 3, 6, 157, 314, 471, 942
979 : 1, 11, 89, 979
921 : 1, 3, 307, 921
445 : 1, 5, 89, 445
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 942,979,921,445, is 1.
Now, the common factors can be found like this.
942:2x 3x 157
979:11x 89
921:3x 307
445:5x 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 89 = 267
Therefore, the value for common factors is 267.
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 = 377966436210/(1x267)
LCM = 377966436210/267
LCM = 1415604630
Thus, we can understand that the LCM of 942,979,921,445 is 1415604630.
