Given numbers are 942,278,939,139
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 942,278,939,139 is 40983594.
Find LCM of 942,278,939,139 with Prime Factorization
| 2 | 942, 278, 939, 139 |
| 3 | 471, 139, 939, 139 |
| 139 | 157, 139, 313, 139 |
| 157, 1, 313, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 139 x 157 x 1 x 313 x 1 = 40983594
Therefore, the lowest common multiple of 942,278,939,139 is 40983594.
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 278 x 939 x 139 = 34180317396
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
278 : 1, 2, 139, 278
939 : 1, 3, 313, 939
139 : 1, 139
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 942,278,939,139, is 1.
Now, the common factors can be found like this.
942:2x 3x 157
278:2x 139
939:3x 313
139:139
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 139 = 834
Therefore, the value for common factors is 834.
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 = 34180317396/(1x834)
LCM = 34180317396/834
LCM = 40983594
Thus, we can understand that the LCM of 942,278,939,139 is 40983594.
