Given numbers are 297,308,301,671,989
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 297,308,301,671,989 is 501695964.
Find LCM of 297,308,301,671,989 with Prime Factorization
| 7 | 297, 308, 301, 671, 989 |
| 11 | 297, 44, 43, 671, 989 |
| 43 | 27, 4, 43, 61, 989 |
| 27, 4, 1, 61, 23 |
Multiply the prime numbers at the bottom and the left side.
7 x 11 x 43 x 27 x 4 x 1 x 61 x 23 = 501695964
Therefore, the lowest common multiple of 297,308,301,671,989 is 501695964.
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.
297 x 308 x 301 x 671 x 989 = 18272268704844
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.
297 : 1, 3, 9, 11, 27, 33, 99, 297
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
301 : 1, 7, 43, 301
671 : 1, 11, 61, 671
989 : 1, 23, 43, 989
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 297,308,301,671,989, is 1.
Now, the common factors can be found like this.
297:3x 3x 3x 11
308:2x 2x 7x 11
301:7x 43
671:11x 61
989:23x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 11x 11x 43 = 36421
Therefore, the value for common factors is 36421.
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 = 18272268704844/(1x36421)
LCM = 18272268704844/36421
LCM = 501695964
Thus, we can understand that the LCM of 297,308,301,671,989 is 501695964.
