The LCM of 531,546,819,554 is 26769834.
Find LCM of 531,546,819,554 with Prime Factorization
| 2 | 531, 546, 819, 554 |
| 3 | 531, 273, 819, 277 |
| 3 | 177, 91, 273, 277 |
| 7 | 59, 91, 91, 277 |
| 13 | 59, 13, 13, 277 |
| 59, 1, 1, 277 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 7 x 13 x 59 x 1 x 1 x 277 = 26769834
Therefore, the lowest common multiple of 531,546,819,554 is 26769834.
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.
531 x 546 x 819 x 554 = 131546964276
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.
531 : 1, 3, 9, 59, 177, 531
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
554 : 1, 2, 277, 554
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 531,546,819,554, is 1.
Now, the common factors can be found like this.
531:3x 3x 59
546:2x 3x 7x 13
819:3x 3x 7x 13
554:2x 277
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 3x 3x 7x 13 = 4914
Therefore, the value for common factors is 4914.
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 = 131546964276/(1x4914)
LCM = 131546964276/4914
LCM = 26769834
Thus, we can understand that the LCM of 531,546,819,554 is 26769834.
