Given numbers are 789,917,749,107
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 789,917,749,107 is 77415891.
Find LCM of 789,917,749,107 with Prime Factorization
| 7 | 789, 917, 749, 107 |
| 107 | 789, 131, 107, 107 |
| 789, 131, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
7 x 107 x 789 x 131 x 1 x 1 = 77415891
Therefore, the lowest common multiple of 789,917,749,107 is 77415891.
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.
789 x 917 x 749 x 107 = 57984502359
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.
789 : 1, 3, 263, 789
917 : 1, 7, 131, 917
749 : 1, 7, 107, 749
107 : 1, 107
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 789,917,749,107, is 1.
Now, the common factors can be found like this.
789:3x 263
917:7x 131
749:7x 107
107:107
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 107 = 749
Therefore, the value for common factors is 749.
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 = 57984502359/(1x749)
LCM = 57984502359/749
LCM = 77415891
Thus, we can understand that the LCM of 789,917,749,107 is 77415891.
