Given numbers are 112,209,740,781
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 112,209,740,781 is 307464080.
Find LCM of 112,209,740,781 with Prime Factorization
| 2 | 112, 209, 740, 781 |
| 2 | 56, 209, 370, 781 |
| 11 | 28, 209, 185, 781 |
| 28, 19, 185, 71 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 28 x 19 x 185 x 71 = 307464080
Therefore, the lowest common multiple of 112,209,740,781 is 307464080.
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.
112 x 209 x 740 x 781 = 13528419520
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.
112 : 1, 2, 4, 7, 8, 14, 16, 28, 56, 112
209 : 1, 11, 19, 209
740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740
781 : 1, 11, 71, 781
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 112,209,740,781, is 1.
Now, the common factors can be found like this.
112:2x 2x 2x 2x 7
209:11x 19
740:2x 2x 5x 37
781:11x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 11 = 44
Therefore, the value for common factors is 44.
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 = 13528419520/(1x44)
LCM = 13528419520/44
LCM = 307464080
Thus, we can understand that the LCM of 112,209,740,781 is 307464080.
