Given numbers are 231,991,525,769,858
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 231,991,525,769,858 is 114426161850.
Find LCM of 231,991,525,769,858 with Prime Factorization
| 3 | 231, 991, 525, 769, 858 |
| 7 | 77, 991, 175, 769, 286 |
| 11 | 11, 991, 25, 769, 286 |
| 1, 991, 25, 769, 26 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 11 x 1 x 991 x 25 x 769 x 26 = 114426161850
Therefore, the lowest common multiple of 231,991,525,769,858 is 114426161850.
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.
231 x 991 x 525 x 769 x 858 = 79297330162050
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.
231 : 1, 3, 7, 11, 21, 33, 77, 231
991 : 1, 991
525 : 1, 3, 5, 7, 15, 21, 25, 35, 75, 105, 175, 525
769 : 1, 769
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 231,991,525,769,858, is 1.
Now, the common factors can be found like this.
231:3x 7x 11
991:991
525:3x 5x 5x 7
769:769
858:2x 3x 11x 13
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 7x 11 = 693
Therefore, the value for common factors is 693.
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 = 79297330162050/(1x693)
LCM = 79297330162050/693
LCM = 114426161850
Thus, we can understand that the LCM of 231,991,525,769,858 is 114426161850.
