Given numbers are 489,540,797,690,674
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 489,540,797,690,674 is 543747686940.
Find LCM of 489,540,797,690,674 with Prime Factorization
| 2 | 489, 540, 797, 690, 674 |
| 3 | 489, 270, 797, 345, 337 |
| 5 | 163, 90, 797, 115, 337 |
| 163, 18, 797, 23, 337 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 163 x 18 x 797 x 23 x 337 = 543747686940
Therefore, the lowest common multiple of 489,540,797,690,674 is 543747686940.
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.
489 x 540 x 797 x 690 x 674 = 97874583649200
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.
489 : 1, 3, 163, 489
540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540
797 : 1, 797
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
674 : 1, 2, 337, 674
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 489,540,797,690,674, is 1.
Now, the common factors can be found like this.
489:3x 163
540:2x 2x 3x 3x 3x 5
797:797
690:2x 3x 5x 23
674:2x 337
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 3x 3x 5 = 180
Therefore, the value for common factors is 180.
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 = 97874583649200/(1x180)
LCM = 97874583649200/180
LCM = 543747686940
Thus, we can understand that the LCM of 489,540,797,690,674 is 543747686940.
