Given numbers are 542,294,202,489
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 542,294,202,489 is 1311673062.
Find LCM of 542,294,202,489 with Prime Factorization
| 2 | 542, 294, 202, 489 |
| 3 | 271, 147, 101, 489 |
| 271, 49, 101, 163 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 271 x 49 x 101 x 163 = 1311673062
Therefore, the lowest common multiple of 542,294,202,489 is 1311673062.
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.
542 x 294 x 202 x 489 = 15740076744
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.
542 : 1, 2, 271, 542
294 : 1, 2, 3, 6, 7, 14, 21, 42, 49, 98, 147, 294
202 : 1, 2, 101, 202
489 : 1, 3, 163, 489
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 542,294,202,489, is 1.
Now, the common factors can be found like this.
542:2x 271
294:2x 3x 7x 7
202:2x 101
489:3x 163
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 3 = 12
Therefore, the value for common factors is 12.
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 = 15740076744/(1x12)
LCM = 15740076744/12
LCM = 1311673062
Thus, we can understand that the LCM of 542,294,202,489 is 1311673062.
