The LCM of 321,276,713,868 is 6408444.
Find LCM of 321,276,713,868 with Prime Factorization
| 2 | 321, 276, 713, 868 |
| 2 | 321, 138, 713, 434 |
| 3 | 321, 69, 713, 217 |
| 23 | 107, 23, 713, 217 |
| 31 | 107, 1, 31, 217 |
| 107, 1, 1, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 23 x 31 x 107 x 1 x 1 x 7 = 6408444
Therefore, the lowest common multiple of 321,276,713,868 is 6408444.
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.
321 x 276 x 713 x 868 = 54830646864
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.
321 : 1, 3, 107, 321
276 : 1, 2, 3, 4, 6, 12, 23, 46, 69, 92, 138, 276
713 : 1, 23, 31, 713
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 321,276,713,868, is 1.
Now, the common factors can be found like this.
321:3x 107
276:2x 2x 3x 23
713:23x 31
868:2x 2x 7x 31
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 23x 31 = 8556
Therefore, the value for common factors is 8556.
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 = 54830646864/(1x8556)
LCM = 54830646864/8556
LCM = 6408444
Thus, we can understand that the LCM of 321,276,713,868 is 6408444.
