Given numbers are 154,770,815,377,231
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 154,770,815,377,231 is 141951810.
Find LCM of 154,770,815,377,231 with Prime Factorization
| 2 | 154, 770, 815, 377, 231 |
| 5 | 77, 385, 815, 377, 231 |
| 7 | 77, 77, 163, 377, 231 |
| 11 | 11, 11, 163, 377, 33 |
| 1, 1, 163, 377, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 11 x 1 x 1 x 163 x 377 x 3 = 141951810
Therefore, the lowest common multiple of 154,770,815,377,231 is 141951810.
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.
154 x 770 x 815 x 377 x 231 = 8416322814900
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.
154 : 1, 2, 7, 11, 14, 22, 77, 154
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
815 : 1, 5, 163, 815
377 : 1, 13, 29, 377
231 : 1, 3, 7, 11, 21, 33, 77, 231
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 154,770,815,377,231, is 1.
Now, the common factors can be found like this.
154:2x 7x 11
770:2x 5x 7x 11
815:5x 163
377:13x 29
231:3x 7x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 7x 7x 11x 11 = 59290
Therefore, the value for common factors is 59290.
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 = 8416322814900/(1x59290)
LCM = 8416322814900/59290
LCM = 141951810
Thus, we can understand that the LCM of 154,770,815,377,231 is 141951810.
