Find LCM of 276,985,969,646 with Prime Factorization
| 2 | 276, 985, 969, 646 |
| 3 | 138, 985, 969, 323 |
| 17 | 46, 985, 323, 323 |
| 19 | 46, 985, 19, 19 |
| 46, 985, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 19 x 46 x 985 x 1 x 1 = 87810780
Therefore, the lowest common multiple of 276,985,969,646 is 87810780.
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.
276 x 985 x 969 x 646 = 170177291640
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.
276 : 1, 2, 3, 4, 6, 12, 23, 46, 69, 92, 138, 276
985 : 1, 5, 197, 985
969 : 1, 3, 17, 19, 51, 57, 323, 969
646 : 1, 2, 17, 19, 34, 38, 323, 646
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 276,985,969,646, is 1.
Now, the common factors can be found like this.
276:2x 2x 3x 23
985:5x 197
969:3x 17x 19
646:2x 17x 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 17x 19 = 1938
Therefore, the value for common factors is 1938.
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 = 170177291640/(1x1938)
LCM = 170177291640/1938
LCM = 87810780
Thus, we can understand that the LCM of 276,985,969,646 is 87810780.
