Given numbers are 965,672,391,938,161
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 965,672,391,938,161 is 16988230560.
Find LCM of 965,672,391,938,161 with Prime Factorization
| 2 | 965, 672, 391, 938, 161 |
| 7 | 965, 336, 391, 469, 161 |
| 23 | 965, 48, 391, 67, 23 |
| 965, 48, 17, 67, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 23 x 965 x 48 x 17 x 67 x 1 = 16988230560
Therefore, the lowest common multiple of 965,672,391,938,161 is 16988230560.
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.
965 x 672 x 391 x 938 x 161 = 38291471682240
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.
965 : 1, 5, 193, 965
672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672
391 : 1, 17, 23, 391
938 : 1, 2, 7, 14, 67, 134, 469, 938
161 : 1, 7, 23, 161
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 965,672,391,938,161, is 1.
Now, the common factors can be found like this.
965:5x 193
672:2x 2x 2x 2x 2x 3x 7
391:17x 23
938:2x 7x 67
161:7x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 7x 23 = 2254
Therefore, the value for common factors is 2254.
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 = 38291471682240/(1x2254)
LCM = 38291471682240/2254
LCM = 16988230560
Thus, we can understand that the LCM of 965,672,391,938,161 is 16988230560.
