Given numbers are 743,380,138,748,760
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 743,380,138,748,760 is 7286066040.
Find LCM of 743,380,138,748,760 with Prime Factorization
| 2 | 743, 380, 138, 748, 760 |
| 2 | 743, 190, 69, 374, 380 |
| 5 | 743, 95, 69, 187, 190 |
| 19 | 743, 19, 69, 187, 38 |
| 743, 1, 69, 187, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 19 x 743 x 1 x 69 x 187 x 2 = 7286066040
Therefore, the lowest common multiple of 743,380,138,748,760 is 7286066040.
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.
743 x 380 x 138 x 748 x 760 = 22149640761600
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.
743 : 1, 743
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
138 : 1, 2, 3, 6, 23, 46, 69, 138
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
760 : 1, 2, 4, 5, 8, 10, 19, 20, 38, 40, 76, 95, 152, 190, 380, 760
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 743,380,138,748,760, is 1.
Now, the common factors can be found like this.
743:743
380:2x 2x 5x 19
138:2x 3x 23
748:2x 2x 11x 17
760:2x 2x 2x 5x 19
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 2x 2x 2x 5x 19 = 3040
Therefore, the value for common factors is 3040.
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 = 22149640761600/(1x3040)
LCM = 22149640761600/3040
LCM = 7286066040
Thus, we can understand that the LCM of 743,380,138,748,760 is 7286066040.
