Given numbers are 395,833,646,228
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 395,833,646,228 is 75019980.
Find LCM of 395,833,646,228 with Prime Factorization
2 | 395, 833, 646, 228 |
17 | 395, 833, 323, 114 |
19 | 395, 49, 19, 114 |
395, 49, 1, 6 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 19 x 395 x 49 x 1 x 6 = 75019980
Therefore, the lowest common multiple of 395,833,646,228 is 75019980.
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.
395 x 833 x 646 x 228 = 48462907080
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.
395 : 1, 5, 79, 395
833 : 1, 7, 17, 49, 119, 833
646 : 1, 2, 17, 19, 34, 38, 323, 646
228 : 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, 228
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 395,833,646,228, is 1.
Now, the common factors can be found like this.
395:5x 79
833:7x 7x 17
646:2x 17x 19
228:2x 2x 3x 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 17x 19 = 646
Therefore, the value for common factors is 646.
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 = 48462907080/(1x646)
LCM = 48462907080/646
LCM = 75019980
Thus, we can understand that the LCM of 395,833,646,228 is 75019980.
