Given numbers are 762,381,309,147
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 762,381,309,147 is 3845814.
Find LCM of 762,381,309,147 with Prime Factorization
| 3 | 762, 381, 309, 147 |
| 127 | 254, 127, 103, 49 |
| 2, 1, 103, 49 |
Multiply the prime numbers at the bottom and the left side.
3 x 127 x 2 x 1 x 103 x 49 = 3845814
Therefore, the lowest common multiple of 762,381,309,147 is 3845814.
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.
762 x 381 x 309 x 147 = 13187296206
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.
762 : 1, 2, 3, 6, 127, 254, 381, 762
381 : 1, 3, 127, 381
309 : 1, 3, 103, 309
147 : 1, 3, 7, 21, 49, 147
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 762,381,309,147, is 3.
Now, the common factors can be found like this.
762:2x 3x 127
381:3x 127
309:3x 103
147:3x 7x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 127 = 1143
Therefore, the value for common factors is 1143.
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 = 13187296206/(3x1143)
LCM = 13187296206/3429
LCM = 3845814
Thus, we can understand that the LCM of 762,381,309,147 is 3845814.
