Given numbers are 844,847,693,278
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 844,847,693,278 is 894299868.
Find LCM of 844,847,693,278 with Prime Factorization
| 2 | 844, 847, 693, 278 |
| 7 | 422, 847, 693, 139 |
| 11 | 422, 121, 99, 139 |
| 422, 11, 9, 139 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 11 x 422 x 11 x 9 x 139 = 894299868
Therefore, the lowest common multiple of 844,847,693,278 is 894299868.
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.
844 x 847 x 693 x 278 = 137722179672
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.
844 : 1, 2, 4, 211, 422, 844
847 : 1, 7, 11, 77, 121, 847
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
278 : 1, 2, 139, 278
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 844,847,693,278, is 1.
Now, the common factors can be found like this.
844:2x 2x 211
847:7x 11x 11
693:3x 3x 7x 11
278:2x 139
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 11 = 154
Therefore, the value for common factors is 154.
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 = 137722179672/(1x154)
LCM = 137722179672/154
LCM = 894299868
Thus, we can understand that the LCM of 844,847,693,278 is 894299868.
