Given numbers are 345,524,621,835
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 345,524,621,835 is 271712340.
Find LCM of 345,524,621,835 with Prime Factorization
| 3 | 345, 524, 621, 835 |
| 5 | 115, 524, 207, 835 |
| 23 | 23, 524, 207, 167 |
| 1, 524, 9, 167 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 23 x 1 x 524 x 9 x 167 = 271712340
Therefore, the lowest common multiple of 345,524,621,835 is 271712340.
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.
345 x 524 x 621 x 835 = 93740757300
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.
345 : 1, 3, 5, 15, 23, 69, 115, 345
524 : 1, 2, 4, 131, 262, 524
621 : 1, 3, 9, 23, 27, 69, 207, 621
835 : 1, 5, 167, 835
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 345,524,621,835, is 1.
Now, the common factors can be found like this.
345:3x 5x 23
524:2x 2x 131
621:3x 3x 3x 23
835:5x 167
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 23 = 345
Therefore, the value for common factors is 345.
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 = 93740757300/(1x345)
LCM = 93740757300/345
LCM = 271712340
Thus, we can understand that the LCM of 345,524,621,835 is 271712340.
