Find LCM of 281,786,945,835,476 with Prime Factorization
| 2 | 281, 786, 945, 835, 476 |
| 3 | 281, 393, 945, 835, 238 |
| 5 | 281, 131, 315, 835, 238 |
| 7 | 281, 131, 63, 167, 238 |
| 281, 131, 9, 167, 34 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 281 x 131 x 9 x 167 x 34 = 395034301620
Therefore, the lowest common multiple of 281,786,945,835,476 is 395034301620.
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 786 x 945 x 835 x 476 = 82957203340200
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
786 : 1, 2, 3, 6, 131, 262, 393, 786
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
835 : 1, 5, 167, 835
476 : 1, 2, 4, 7, 14, 17, 28, 34, 68, 119, 238, 476
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 281,786,945,835,476, is 1.
Now, the common factors can be found like this.
281:281
786:2x 3x 131
945:3x 3x 3x 5x 7
835:5x 167
476:2x 2x 7x 17
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 5x 7 = 210
Therefore, the value for common factors is 210.
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 = 82957203340200/(1x210)
LCM = 82957203340200/210
LCM = 395034301620
Thus, we can understand that the LCM of 281,786,945,835,476 is 395034301620.
