Given numbers are 544,842,861,646
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 544,842,861,646 is 3746603616.
Find LCM of 544,842,861,646 with Prime Factorization
| 2 | 544, 842, 861, 646 |
| 17 | 272, 421, 861, 323 |
| 16, 421, 861, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 16 x 421 x 861 x 19 = 3746603616
Therefore, the lowest common multiple of 544,842,861,646 is 3746603616.
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.
544 x 842 x 861 x 646 = 254769045888
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.
544 : 1, 2, 4, 8, 16, 17, 32, 34, 68, 136, 272, 544
842 : 1, 2, 421, 842
861 : 1, 3, 7, 21, 41, 123, 287, 861
646 : 1, 2, 17, 19, 34, 38, 323, 646
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 544,842,861,646, is 1.
Now, the common factors can be found like this.
544:2x 2x 2x 2x 2x 17
842:2x 421
861:3x 7x 41
646:2x 17x 19
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 17 = 68
Therefore, the value for common factors is 68.
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 = 254769045888/(1x68)
LCM = 254769045888/68
LCM = 3746603616
Thus, we can understand that the LCM of 544,842,861,646 is 3746603616.
