Given numbers are 782,134,391
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 782,134,391 is 52394.
Find LCM of 782,134,391 with Prime Factorization
| 2 | 782, 134, 391 |
| 17 | 391, 67, 391 |
| 23 | 23, 67, 23 |
| 1, 67, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 23 x 1 x 67 x 1 = 52394
Therefore, the lowest common multiple of 782,134,391 is 52394.
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.
782 x 134 x 391 = 40972108
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.
782 : 1, 2, 17, 23, 34, 46, 391, 782
134 : 1, 2, 67, 134
391 : 1, 17, 23, 391
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 782,134,391, is 1.
Now, the common factors can be found like this.
782:2x 17x 23
134:2x 67
391:17x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 17x 23 = 782
Therefore, the value for common factors is 782.
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 = 40972108/(1x782)
LCM = 40972108/782
LCM = 52394
Thus, we can understand that the LCM of 782,134,391 is 52394.
