Find LCM of 832,864,561,661 with Prime Factorization
| 2 | 832, 864, 561, 661 |
| 2 | 416, 432, 561, 661 |
| 2 | 208, 216, 561, 661 |
| 2 | 104, 108, 561, 661 |
| 2 | 52, 54, 561, 661 |
| 3 | 26, 27, 561, 661 |
| 26, 9, 187, 661 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 3 x 26 x 9 x 187 x 661 = 2776707648
Therefore, the lowest common multiple of 832,864,561,661 is 2776707648.
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.
832 x 864 x 561 x 661 = 266563934208
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.
832 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 64, 104, 208, 416, 832
864 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 72, 96, 108, 144, 216, 288, 432, 864
561 : 1, 3, 11, 17, 33, 51, 187, 561
661 : 1, 661
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 832,864,561,661, is 1.
Now, the common factors can be found like this.
832:2x 2x 2x 2x 2x 2x 13
864:2x 2x 2x 2x 2x 3x 3x 3
561:3x 11x 17
661:661
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 2x 2x 3 = 96
Therefore, the value for common factors is 96.
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 = 266563934208/(1x96)
LCM = 266563934208/96
LCM = 2776707648
Thus, we can understand that the LCM of 832,864,561,661 is 2776707648.
