The LCM of 856,642,551,564 is 66503496.
Find LCM of 856,642,551,564 with Prime Factorization
| 2 | 856, 642, 551, 564 |
| 2 | 428, 321, 551, 282 |
| 3 | 214, 321, 551, 141 |
| 107 | 214, 107, 551, 47 |
| 2, 1, 551, 47 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 107 x 2 x 1 x 551 x 47 = 66503496
Therefore, the lowest common multiple of 856,642,551,564 is 66503496.
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.
856 x 642 x 551 x 564 = 170780977728
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.
856 : 1, 2, 4, 8, 107, 214, 428, 856
642 : 1, 2, 3, 6, 107, 214, 321, 642
551 : 1, 19, 29, 551
564 : 1, 2, 3, 4, 6, 12, 47, 94, 141, 188, 282, 564
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 856,642,551,564, is 1.
Now, the common factors can be found like this.
856:2x 2x 2x 107
642:2x 3x 107
551:19x 29
564:2x 2x 3x 47
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 3x 107 = 2568
Therefore, the value for common factors is 2568.
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 = 170780977728/(1x2568)
LCM = 170780977728/2568
LCM = 66503496
Thus, we can understand that the LCM of 856,642,551,564 is 66503496.
