Find LCM of 931,320,532,725,987 with Prime Factorization
| 2 | 931, 320, 532, 725, 987 |
| 2 | 931, 160, 266, 725, 987 |
| 5 | 931, 80, 133, 725, 987 |
| 7 | 931, 16, 133, 145, 987 |
| 19 | 19, 16, 133, 145, 141 |
| 1, 16, 7, 145, 141 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 19 x 1 x 16 x 7 x 145 x 141 = 6090974400
Therefore, the lowest common multiple of 931,320,532,725,987 is 6090974400.
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.
931 x 320 x 532 x 725 x 987 = 113413943328000
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.
931 : 1, 7, 19, 49, 133, 931
320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320
532 : 1, 2, 4, 7, 14, 19, 28, 38, 76, 133, 266, 532
725 : 1, 5, 25, 29, 145, 725
987 : 1, 3, 7, 21, 47, 141, 329, 987
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 931,320,532,725,987, is 1.
Now, the common factors can be found like this.
931:7x 7x 19
320:2x 2x 2x 2x 2x 2x 5
532:2x 2x 7x 19
725:5x 5x 29
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 2x 5x 7x 7x 19 = 18620
Therefore, the value for common factors is 18620.
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 = 113413943328000/(1x18620)
LCM = 113413943328000/18620
LCM = 6090974400
Thus, we can understand that the LCM of 931,320,532,725,987 is 6090974400.
