The LCM of 646,773,193,408,164 is 47417038248.
Find LCM of 646,773,193,408,164 with Prime Factorization
| 2 | 646, 773, 193, 408, 164 |
| 2 | 323, 773, 193, 204, 82 |
| 17 | 323, 773, 193, 102, 41 |
| 19, 773, 193, 6, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 17 x 19 x 773 x 193 x 6 x 41 = 47417038248
Therefore, the lowest common multiple of 646,773,193,408,164 is 47417038248.
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.
646 x 773 x 193 x 408 x 164 = 6448717201728
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.
646 : 1, 2, 17, 19, 34, 38, 323, 646
773 : 1, 773
193 : 1, 193
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
164 : 1, 2, 4, 41, 82, 164
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,773,193,408,164, is 1.
Now, the common factors can be found like this.
646:2x 17x 19
773:773
193:193
408:2x 2x 2x 3x 17
164:2x 2x 41
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 17 = 136
Therefore, the value for common factors is 136.
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 = 6448717201728/(1x136)
LCM = 6448717201728/136
LCM = 47417038248
Thus, we can understand that the LCM of 646,773,193,408,164 is 47417038248.
