The LCM of 532,840,987,761 is 570841320.
Find LCM of 532,840,987,761 with Prime Factorization
| 2 | 532, 840, 987, 761 |
| 2 | 266, 420, 987, 761 |
| 3 | 133, 210, 987, 761 |
| 7 | 133, 70, 329, 761 |
| 19, 10, 47, 761 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 19 x 10 x 47 x 761 = 570841320
Therefore, the lowest common multiple of 532,840,987,761 is 570841320.
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.
532 x 840 x 987 x 761 = 335654696160
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.
532 : 1, 2, 4, 7, 14, 19, 28, 38, 76, 133, 266, 532
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
987 : 1, 3, 7, 21, 47, 141, 329, 987
761 : 1, 761
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 532,840,987,761, is 1.
Now, the common factors can be found like this.
532:2x 2x 7x 19
840:2x 2x 2x 3x 5x 7
987:3x 7x 47
761:761
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 7x 7 = 588
Therefore, the value for common factors is 588.
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 = 335654696160/(1x588)
LCM = 335654696160/588
LCM = 570841320
Thus, we can understand that the LCM of 532,840,987,761 is 570841320.
