Find LCM of 721,746,396,319,399 with Prime Factorization
| 2 | 721, 746, 396, 319, 399 |
| 3 | 721, 373, 198, 319, 399 |
| 7 | 721, 373, 66, 319, 133 |
| 11 | 103, 373, 66, 319, 19 |
| 103, 373, 6, 29, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 11 x 103 x 373 x 6 x 29 x 19 = 58680104868
Therefore, the lowest common multiple of 721,746,396,319,399 is 58680104868.
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.
721 x 746 x 396 x 319 x 399 = 27110208449016
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.
721 : 1, 7, 103, 721
746 : 1, 2, 373, 746
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
319 : 1, 11, 29, 319
399 : 1, 3, 7, 19, 21, 57, 133, 399
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,746,396,319,399, is 1.
Now, the common factors can be found like this.
721:7x 103
746:2x 373
396:2x 2x 3x 3x 11
319:11x 29
399:3x 7x 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 7x 11 = 462
Therefore, the value for common factors is 462.
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 = 27110208449016/(1x462)
LCM = 27110208449016/462
LCM = 58680104868
Thus, we can understand that the LCM of 721,746,396,319,399 is 58680104868.
