Given numbers are 549,393,917,878
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 549,393,917,878 is 442014174.
Find LCM of 549,393,917,878 with Prime Factorization
| 3 | 549, 393, 917, 878 |
| 131 | 183, 131, 917, 878 |
| 183, 1, 7, 878 |
Multiply the prime numbers at the bottom and the left side.
3 x 131 x 183 x 1 x 7 x 878 = 442014174
Therefore, the lowest common multiple of 549,393,917,878 is 442014174.
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.
549 x 393 x 917 x 878 = 173711570382
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.
549 : 1, 3, 9, 61, 183, 549
393 : 1, 3, 131, 393
917 : 1, 7, 131, 917
878 : 1, 2, 439, 878
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 549,393,917,878, is 1.
Now, the common factors can be found like this.
549:3x 3x 61
393:3x 131
917:7x 131
878:2x 439
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 131 = 393
Therefore, the value for common factors is 393.
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 = 173711570382/(1x393)
LCM = 173711570382/393
LCM = 442014174
Thus, we can understand that the LCM of 549,393,917,878 is 442014174.
