Given numbers are 687,705,849,893
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 687,705,849,893 is 868089765.
Find LCM of 687,705,849,893 with Prime Factorization
3 | 687, 705, 849, 893 |
47 | 229, 235, 283, 893 |
229, 5, 283, 19 |
Multiply the prime numbers at the bottom and the left side.
3 x 47 x 229 x 5 x 283 x 19 = 868089765
Therefore, the lowest common multiple of 687,705,849,893 is 868089765.
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.
687 x 705 x 849 x 893 = 367201970595
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.
687 : 1, 3, 229, 687
705 : 1, 3, 5, 15, 47, 141, 235, 705
849 : 1, 3, 283, 849
893 : 1, 19, 47, 893
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 687,705,849,893, is 1.
Now, the common factors can be found like this.
687:3x 229
705:3x 5x 47
849:3x 283
893:19x 47
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 47 = 423
Therefore, the value for common factors is 423.
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 = 367201970595/(1x423)
LCM = 367201970595/423
LCM = 868089765
Thus, we can understand that the LCM of 687,705,849,893 is 868089765.
