The LCM of 801,765,378,404,320 is 9242130240.
Find LCM of 801,765,378,404,320 with Prime Factorization
| 2 | 801, 765, 378, 404, 320 |
| 2 | 801, 765, 189, 202, 160 |
| 3 | 801, 765, 189, 101, 80 |
| 3 | 267, 255, 63, 101, 80 |
| 5 | 89, 85, 21, 101, 80 |
| 89, 17, 21, 101, 16 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 89 x 17 x 21 x 101 x 16 = 9242130240
Therefore, the lowest common multiple of 801,765,378,404,320 is 9242130240.
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.
801 x 765 x 378 x 404 x 320 = 29944501977600
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.
801 : 1, 3, 9, 89, 267, 801
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
404 : 1, 2, 4, 101, 202, 404
320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 801,765,378,404,320, is 1.
Now, the common factors can be found like this.
801:3x 3x 89
765:3x 3x 5x 17
378:2x 3x 3x 3x 7
404:2x 2x 101
320:2x 2x 2x 2x 2x 2x 5
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 3x 3x 3x 5 = 3240
Therefore, the value for common factors is 3240.
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 = 29944501977600/(1x3240)
LCM = 29944501977600/3240
LCM = 9242130240
Thus, we can understand that the LCM of 801,765,378,404,320 is 9242130240.
