Given numbers are 824,672,234,821
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 824,672,234,821 is 2216227104.
Find LCM of 824,672,234,821 with Prime Factorization
| 2 | 824, 672, 234, 821 |
| 2 | 412, 336, 117, 821 |
| 2 | 206, 168, 117, 821 |
| 3 | 103, 84, 117, 821 |
| 103, 28, 39, 821 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 103 x 28 x 39 x 821 = 2216227104
Therefore, the lowest common multiple of 824,672,234,821 is 2216227104.
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.
824 x 672 x 234 x 821 = 106378900992
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.
824 : 1, 2, 4, 8, 103, 206, 412, 824
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
234 : 1, 2, 3, 6, 9, 13, 18, 26, 39, 78, 117, 234
821 : 1, 821
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 824,672,234,821, is 1.
Now, the common factors can be found like this.
824:2x 2x 2x 103
672:2x 2x 2x 2x 2x 3x 7
234:2x 3x 3x 13
821:821
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 2x 2x 3 = 48
Therefore, the value for common factors is 48.
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 = 106378900992/(1x48)
LCM = 106378900992/48
LCM = 2216227104
Thus, we can understand that the LCM of 824,672,234,821 is 2216227104.
