Given numbers are 675,157,385,861
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 675,157,385,861 is 334563075.
Find LCM of 675,157,385,861 with Prime Factorization
| 3 | 675, 157, 385, 861 |
| 5 | 225, 157, 385, 287 |
| 7 | 45, 157, 77, 287 |
| 45, 157, 11, 41 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 7 x 45 x 157 x 11 x 41 = 334563075
Therefore, the lowest common multiple of 675,157,385,861 is 334563075.
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.
675 x 157 x 385 x 861 = 35129122875
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.
675 : 1, 3, 5, 9, 15, 25, 27, 45, 75, 135, 225, 675
157 : 1, 157
385 : 1, 5, 7, 11, 35, 55, 77, 385
861 : 1, 3, 7, 21, 41, 123, 287, 861
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 675,157,385,861, is 1.
Now, the common factors can be found like this.
675:3x 3x 3x 5x 5
157:157
385:5x 7x 11
861:3x 7x 41
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 7 = 105
Therefore, the value for common factors is 105.
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 = 35129122875/(1x105)
LCM = 35129122875/105
LCM = 334563075
Thus, we can understand that the LCM of 675,157,385,861 is 334563075.
