Find LCM of 828,278,836,672,765 with Prime Factorization
| 2 | 828, 278, 836, 672, 765 |
| 2 | 414, 139, 418, 336, 765 |
| 3 | 207, 139, 209, 168, 765 |
| 3 | 69, 139, 209, 56, 255 |
| 23, 139, 209, 56, 85 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 23 x 139 x 209 x 56 x 85 = 114498125280
Therefore, the lowest common multiple of 828,278,836,672,765 is 114498125280.
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.
828 x 278 x 836 x 672 x 765 = 98926380241920
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.
828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828
278 : 1, 2, 139, 278
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 828,278,836,672,765, is 1.
Now, the common factors can be found like this.
828:2x 2x 3x 3x 23
278:2x 139
836:2x 2x 11x 19
672:2x 2x 2x 2x 2x 3x 7
765:3x 3x 5x 17
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 3x 3x 3 = 864
Therefore, the value for common factors is 864.
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 = 98926380241920/(1x864)
LCM = 98926380241920/864
LCM = 114498125280
Thus, we can understand that the LCM of 828,278,836,672,765 is 114498125280.
