Given numbers are 257,867,771,880
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 257,867,771,880 is 196080720.
Find LCM of 257,867,771,880 with Prime Factorization
| 3 | 257, 867, 771, 880 |
| 257 | 257, 289, 257, 880 |
| 1, 289, 1, 880 |
Multiply the prime numbers at the bottom and the left side.
3 x 257 x 1 x 289 x 1 x 880 = 196080720
Therefore, the lowest common multiple of 257,867,771,880 is 196080720.
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.
257 x 867 x 771 x 880 = 151178235120
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.
257 : 1, 257
867 : 1, 3, 17, 51, 289, 867
771 : 1, 3, 257, 771
880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 257,867,771,880, is 1.
Now, the common factors can be found like this.
257:257
867:3x 17x 17
771:3x 257
880:2x 2x 2x 2x 5x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 257 = 771
Therefore, the value for common factors is 771.
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 = 151178235120/(1x771)
LCM = 151178235120/771
LCM = 196080720
Thus, we can understand that the LCM of 257,867,771,880 is 196080720.
