Given numbers are 612,912,911,342
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 612,912,911,342 is 42372432.
Find LCM of 612,912,911,342 with Prime Factorization
| 2 | 612, 912, 911, 342 |
| 2 | 306, 456, 911, 171 |
| 3 | 153, 228, 911, 171 |
| 3 | 51, 76, 911, 57 |
| 19 | 17, 76, 911, 19 |
| 17, 4, 911, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 19 x 17 x 4 x 911 x 1 = 42372432
Therefore, the lowest common multiple of 612,912,911,342 is 42372432.
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.
612 x 912 x 911 x 342 = 173896460928
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.
612 : 1, 2, 3, 4, 6, 9, 12, 17, 18, 34, 36, 51, 68, 102, 153, 204, 306, 612
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
911 : 1, 911
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 612,912,911,342, is 1.
Now, the common factors can be found like this.
612:2x 2x 3x 3x 17
912:2x 2x 2x 2x 3x 19
911:911
342:2x 3x 3x 19
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 3x 3x 3x 19 = 4104
Therefore, the value for common factors is 4104.
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 = 173896460928/(1x4104)
LCM = 173896460928/4104
LCM = 42372432
Thus, we can understand that the LCM of 612,912,911,342 is 42372432.
