Given numbers are 282,803,768,921
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 282,803,768,921 is 8898422016.
Find LCM of 282,803,768,921 with Prime Factorization
| 2 | 282, 803, 768, 921 |
| 3 | 141, 803, 384, 921 |
| 47, 803, 128, 307 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 47 x 803 x 128 x 307 = 8898422016
Therefore, the lowest common multiple of 282,803,768,921 is 8898422016.
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.
282 x 803 x 768 x 921 = 160171596288
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.
282 : 1, 2, 3, 6, 47, 94, 141, 282
803 : 1, 11, 73, 803
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
921 : 1, 3, 307, 921
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 282,803,768,921, is 1.
Now, the common factors can be found like this.
282:2x 3x 47
803:11x 73
768:2x 2x 2x 2x 2x 2x 2x 2x 3
921:3x 307
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3 = 18
Therefore, the value for common factors is 18.
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 = 160171596288/(1x18)
LCM = 160171596288/18
LCM = 8898422016
Thus, we can understand that the LCM of 282,803,768,921 is 8898422016.
