The LCM of 646,734,252,812,948 is 68437512612.
Find LCM of 646,734,252,812,948 with Prime Factorization
| 2 | 646, 734, 252, 812, 948 |
| 2 | 323, 367, 126, 406, 474 |
| 3 | 323, 367, 63, 203, 237 |
| 7 | 323, 367, 21, 203, 79 |
| 323, 367, 3, 29, 79 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 323 x 367 x 3 x 29 x 79 = 68437512612
Therefore, the lowest common multiple of 646,734,252,812,948 is 68437512612.
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.
646 x 734 x 252 x 812 x 948 = 91980016950528
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.
646 : 1, 2, 17, 19, 34, 38, 323, 646
734 : 1, 2, 367, 734
252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
948 : 1, 2, 3, 4, 6, 12, 79, 158, 237, 316, 474, 948
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,734,252,812,948, is 2.
Now, the common factors can be found like this.
646:2x 17x 19
734:2x 367
252:2x 2x 3x 3x 7
812:2x 2x 7x 29
948:2x 2x 3x 79
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 7 = 672
Therefore, the value for common factors is 672.
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 = 91980016950528/(2x672)
LCM = 91980016950528/1344
LCM = 68437512612
Thus, we can understand that the LCM of 646,734,252,812,948 is 68437512612.
