Find LCM of 646,537,829,754,741 with Prime Factorization
| 2 | 646, 537, 829, 754, 741 |
| 3 | 323, 537, 829, 377, 741 |
| 13 | 323, 179, 829, 377, 247 |
| 19 | 323, 179, 829, 29, 19 |
| 17, 179, 829, 29, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 19 x 17 x 179 x 829 x 29 x 1 = 108418322766
Therefore, the lowest common multiple of 646,537,829,754,741 is 108418322766.
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.
646 x 537 x 829 x 754 x 741 = 160675954339212
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.
646 : 1, 2, 17, 19, 34, 38, 323, 646
537 : 1, 3, 179, 537
829 : 1, 829
754 : 1, 2, 13, 26, 29, 58, 377, 754
741 : 1, 3, 13, 19, 39, 57, 247, 741
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,537,829,754,741, is 1.
Now, the common factors can be found like this.
646:2x 17x 19
537:3x 179
829:829
754:2x 13x 29
741:3x 13x 19
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 13x 19 = 1482
Therefore, the value for common factors is 1482.
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 = 160675954339212/(1x1482)
LCM = 160675954339212/1482
LCM = 108418322766
Thus, we can understand that the LCM of 646,537,829,754,741 is 108418322766.
