Find LCM of 768,836,254,429,121 with Prime Factorization
| 2 | 768, 836, 254, 429, 121 |
| 2 | 384, 418, 127, 429, 121 |
| 3 | 192, 209, 127, 429, 121 |
| 11 | 64, 209, 127, 143, 121 |
| 64, 19, 127, 13, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 64 x 19 x 127 x 13 x 11 = 2915058432
Therefore, the lowest common multiple of 768,836,254,429,121 is 2915058432.
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.
768 x 836 x 254 x 429 x 121 = 8465329686528
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.
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
254 : 1, 2, 127, 254
429 : 1, 3, 11, 13, 33, 39, 143, 429
121 : 1, 11, 121
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 768,836,254,429,121, is 1.
Now, the common factors can be found like this.
768:2x 2x 2x 2x 2x 2x 2x 2x 3
836:2x 2x 11x 19
254:2x 127
429:3x 11x 13
121:11x 11
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 11x 11 = 2904
Therefore, the value for common factors is 2904.
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 = 8465329686528/(1x2904)
LCM = 8465329686528/2904
LCM = 2915058432
Thus, we can understand that the LCM of 768,836,254,429,121 is 2915058432.
