The LCM of 252,257,729,980 is 183605940.
Find LCM of 252,257,729,980 with Prime Factorization
| 2 | 252, 257, 729, 980 |
| 2 | 126, 257, 729, 490 |
| 3 | 63, 257, 729, 245 |
| 3 | 21, 257, 243, 245 |
| 7 | 7, 257, 81, 245 |
| 1, 257, 81, 35 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 7 x 1 x 257 x 81 x 35 = 183605940
Therefore, the lowest common multiple of 252,257,729,980 is 183605940.
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.
252 x 257 x 729 x 980 = 46268696880
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.
252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252
257 : 1, 257
729 : 1, 3, 9, 27, 81, 243, 729
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 252,257,729,980, is 1.
Now, the common factors can be found like this.
252:2x 2x 3x 3x 7
257:257
729:3x 3x 3x 3x 3x 3
980:2x 2x 5x 7x 7
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 3x 3x 7 = 252
Therefore, the value for common factors is 252.
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 = 46268696880/(1x252)
LCM = 46268696880/252
LCM = 183605940
Thus, we can understand that the LCM of 252,257,729,980 is 183605940.
