The LCM of 531,762,846,987 is 44373546.
Find LCM of 531,762,846,987 with Prime Factorization
| 2 | 531, 762, 846, 987 |
| 3 | 531, 381, 423, 987 |
| 3 | 177, 127, 141, 329 |
| 47 | 59, 127, 47, 329 |
| 59, 127, 1, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 47 x 59 x 127 x 1 x 7 = 44373546
Therefore, the lowest common multiple of 531,762,846,987 is 44373546.
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 762 x 846 x 987 = 337860179244
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
762 : 1, 2, 3, 6, 127, 254, 381, 762
846 : 1, 2, 3, 6, 9, 18, 47, 94, 141, 282, 423, 846
987 : 1, 3, 7, 21, 47, 141, 329, 987
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 531,762,846,987, is 3.
Now, the common factors can be found like this.
531:3x 3x 59
762:2x 3x 127
846:2x 3x 3x 47
987:3x 7x 47
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 47 = 2538
Therefore, the value for common factors is 2538.
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 = 337860179244/(3x2538)
LCM = 337860179244/7614
LCM = 44373546
Thus, we can understand that the LCM of 531,762,846,987 is 44373546.
