Find LCM of 279,720,781,814,923 with Prime Factorization
2 | 279, 720, 781, 814, 923 |
3 | 279, 360, 781, 407, 923 |
3 | 93, 120, 781, 407, 923 |
11 | 31, 40, 781, 407, 923 |
71 | 31, 40, 71, 37, 923 |
31, 40, 1, 37, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 11 x 71 x 31 x 40 x 1 x 37 x 13 = 8384753520
Therefore, the lowest common multiple of 279,720,781,814,923 is 8384753520.
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.
279 x 720 x 781 x 814 x 923 = 117872864984160
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.
279 : 1, 3, 9, 31, 93, 279
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
781 : 1, 11, 71, 781
814 : 1, 2, 11, 22, 37, 74, 407, 814
923 : 1, 13, 71, 923
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 279,720,781,814,923, is 1.
Now, the common factors can be found like this.
279:3x 3x 31
720:2x 2x 2x 2x 3x 3x 5
781:11x 71
814:2x 11x 37
923:13x 71
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 3x 11x 71 = 14058
Therefore, the value for common factors is 14058.
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 = 117872864984160/(1x14058)
LCM = 117872864984160/14058
LCM = 8384753520
Thus, we can understand that the LCM of 279,720,781,814,923 is 8384753520.
