The LCM of 281,562,668,856 is 40169512.
Find LCM of 281,562,668,856 with Prime Factorization
| 2 | 281, 562, 668, 856 |
| 2 | 281, 281, 334, 428 |
| 281 | 281, 281, 167, 214 |
| 1, 1, 167, 214 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 281 x 1 x 1 x 167 x 214 = 40169512
Therefore, the lowest common multiple of 281,562,668,856 is 40169512.
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.
281 x 562 x 668 x 856 = 90301062976
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.
281 : 1, 281
562 : 1, 2, 281, 562
668 : 1, 2, 4, 167, 334, 668
856 : 1, 2, 4, 8, 107, 214, 428, 856
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 281,562,668,856, is 1.
Now, the common factors can be found like this.
281:281
562:2x 281
668:2x 2x 167
856:2x 2x 2x 107
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 281 = 2248
Therefore, the value for common factors is 2248.
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 = 90301062976/(1x2248)
LCM = 90301062976/2248
LCM = 40169512
Thus, we can understand that the LCM of 281,562,668,856 is 40169512.
