The LCM of 874,329,798,257 is 221697966.
Find LCM of 874,329,798,257 with Prime Factorization
| 2 | 874, 329, 798, 257 |
| 7 | 437, 329, 399, 257 |
| 19 | 437, 47, 57, 257 |
| 23, 47, 3, 257 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 19 x 23 x 47 x 3 x 257 = 221697966
Therefore, the lowest common multiple of 874,329,798,257 is 221697966.
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.
874 x 329 x 798 x 257 = 58971658956
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.
874 : 1, 2, 19, 23, 38, 46, 437, 874
329 : 1, 7, 47, 329
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
257 : 1, 257
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 874,329,798,257, is 1.
Now, the common factors can be found like this.
874:2x 19x 23
329:7x 47
798:2x 3x 7x 19
257:257
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 19 = 266
Therefore, the value for common factors is 266.
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 = 58971658956/(1x266)
LCM = 58971658956/266
LCM = 221697966
Thus, we can understand that the LCM of 874,329,798,257 is 221697966.
