Given numbers are 554,218,672,831
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 554,218,672,831 is 20289696.
Find LCM of 554,218,672,831 with Prime Factorization
| 2 | 554, 218, 672, 831 |
| 3 | 277, 109, 336, 831 |
| 277 | 277, 109, 112, 277 |
| 1, 109, 112, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 277 x 1 x 109 x 112 x 1 = 20289696
Therefore, the lowest common multiple of 554,218,672,831 is 20289696.
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.
554 x 218 x 672 x 831 = 67442949504
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.
554 : 1, 2, 277, 554
218 : 1, 2, 109, 218
672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672
831 : 1, 3, 277, 831
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 554,218,672,831, is 1.
Now, the common factors can be found like this.
554:2x 277
218:2x 109
672:2x 2x 2x 2x 2x 3x 7
831:3x 277
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 277 = 3324
Therefore, the value for common factors is 3324.
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 = 67442949504/(1x3324)
LCM = 67442949504/3324
LCM = 20289696
Thus, we can understand that the LCM of 554,218,672,831 is 20289696.
