Find LCM of 261,967,493,784,261 with Prime Factorization
| 3 | 261, 967, 493, 784, 261 |
| 3 | 87, 967, 493, 784, 87 |
| 29 | 29, 967, 493, 784, 29 |
| 1, 967, 17, 784, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 29 x 1 x 967 x 17 x 784 x 1 = 3363813936
Therefore, the lowest common multiple of 261,967,493,784,261 is 3363813936.
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.
261 x 967 x 493 x 784 x 261 = 25460707681584
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.
261 : 1, 3, 9, 29, 87, 261
967 : 1, 967
493 : 1, 17, 29, 493
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
261 : 1, 3, 9, 29, 87, 261
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 261,967,493,784,261, is 1.
Now, the common factors can be found like this.
261:3x 3x 29
967:967
493:17x 29
784:2x 2x 2x 2x 7x 7
261:3x 3x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 29x 29 = 7569
Therefore, the value for common factors is 7569.
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 = 25460707681584/(1x7569)
LCM = 25460707681584/7569
LCM = 3363813936
Thus, we can understand that the LCM of 261,967,493,784,261 is 3363813936.
