Given numbers are 307,667,420,214,161
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 307,667,420,214,161 is 9202318860.
Find LCM of 307,667,420,214,161 with Prime Factorization
| 2 | 307, 667, 420, 214, 161 |
| 7 | 307, 667, 210, 107, 161 |
| 23 | 307, 667, 30, 107, 23 |
| 307, 29, 30, 107, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 23 x 307 x 29 x 30 x 107 x 1 = 9202318860
Therefore, the lowest common multiple of 307,667,420,214,161 is 9202318860.
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.
307 x 667 x 420 x 214 x 161 = 2963146672920
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.
307 : 1, 307
667 : 1, 23, 29, 667
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
214 : 1, 2, 107, 214
161 : 1, 7, 23, 161
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 307,667,420,214,161, is 1.
Now, the common factors can be found like this.
307:307
667:23x 29
420:2x 2x 3x 5x 7
214:2x 107
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 23 = 322
Therefore, the value for common factors is 322.
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 = 2963146672920/(1x322)
LCM = 2963146672920/322
LCM = 9202318860
Thus, we can understand that the LCM of 307,667,420,214,161 is 9202318860.
