Given numbers are 540,818,889,669,397
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 540,818,889,669,397 is 17382578470740.
Find LCM of 540,818,889,669,397 with Prime Factorization
| 2 | 540, 818, 889, 669, 397 |
| 3 | 270, 409, 889, 669, 397 |
| 90, 409, 889, 223, 397 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 90 x 409 x 889 x 223 x 397 = 17382578470740
Therefore, the lowest common multiple of 540,818,889,669,397 is 17382578470740.
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.
540 x 818 x 889 x 669 x 397 = 104295470824440
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.
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
818 : 1, 2, 409, 818
889 : 1, 7, 127, 889
669 : 1, 3, 223, 669
397 : 1, 397
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 540,818,889,669,397, is 1.
Now, the common factors can be found like this.
540:2x 2x 3x 3x 3x 5
818:2x 409
889:7x 127
669:3x 223
397:397
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 104295470824440/(1x6)
LCM = 104295470824440/6
LCM = 17382578470740
Thus, we can understand that the LCM of 540,818,889,669,397 is 17382578470740.
