Given numbers are 822,137,375,861
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 822,137,375,861 is 29489250.
Find LCM of 822,137,375,861 with Prime Factorization
| 3 | 822, 137, 375, 861 |
| 137 | 274, 137, 125, 287 |
| 2, 1, 125, 287 |
Multiply the prime numbers at the bottom and the left side.
3 x 137 x 2 x 1 x 125 x 287 = 29489250
Therefore, the lowest common multiple of 822,137,375,861 is 29489250.
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.
822 x 137 x 375 x 861 = 36360245250
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.
822 : 1, 2, 3, 6, 137, 274, 411, 822
137 : 1, 137
375 : 1, 3, 5, 15, 25, 75, 125, 375
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 822,137,375,861, is 1.
Now, the common factors can be found like this.
822:2x 3x 137
137:137
375:3x 5x 5x 5
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 3x 137 = 1233
Therefore, the value for common factors is 1233.
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 = 36360245250/(1x1233)
LCM = 36360245250/1233
LCM = 29489250
Thus, we can understand that the LCM of 822,137,375,861 is 29489250.
