Find LCM of 389,168,638,968,859 with Prime Factorization
| 2 | 389, 168, 638, 968, 859 |
| 2 | 389, 84, 319, 484, 859 |
| 2 | 389, 42, 319, 242, 859 |
| 11 | 389, 21, 319, 121, 859 |
| 389, 21, 29, 11, 859 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 11 x 389 x 21 x 29 x 11 x 859 = 196986024312
Therefore, the lowest common multiple of 389,168,638,968,859 is 196986024312.
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.
389 x 168 x 638 x 968 x 859 = 34669540278912
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.
389 : 1, 389
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
638 : 1, 2, 11, 22, 29, 58, 319, 638
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
859 : 1, 859
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 389,168,638,968,859, is 1.
Now, the common factors can be found like this.
389:389
168:2x 2x 2x 3x 7
638:2x 11x 29
968:2x 2x 2x 11x 11
859:859
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 2x 11 = 176
Therefore, the value for common factors is 176.
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 = 34669540278912/(1x176)
LCM = 34669540278912/176
LCM = 196986024312
Thus, we can understand that the LCM of 389,168,638,968,859 is 196986024312.
