The LCM of 530,988,285,247 is 785460.
Find LCM of 530,988,285,247 with Prime Factorization
| 2 | 530, 988, 285, 247 |
| 5 | 265, 494, 285, 247 |
| 13 | 53, 494, 57, 247 |
| 19 | 53, 38, 57, 19 |
| 53, 2, 3, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 13 x 19 x 53 x 2 x 3 x 1 = 785460
Therefore, the lowest common multiple of 530,988,285,247 is 785460.
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.
530 x 988 x 285 x 247 = 36861637800
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.
530 : 1, 2, 5, 10, 53, 106, 265, 530
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
285 : 1, 3, 5, 15, 19, 57, 95, 285
247 : 1, 13, 19, 247
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 530,988,285,247, is 1.
Now, the common factors can be found like this.
530:2x 5x 53
988:2x 2x 13x 19
285:3x 5x 19
247:13x 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 5x 13x 19x 19 = 46930
Therefore, the value for common factors is 46930.
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 = 36861637800/(1x46930)
LCM = 36861637800/46930
LCM = 785460
Thus, we can understand that the LCM of 530,988,285,247 is 785460.
