Find LCM of 931,990,116,120,634 with Prime Factorization
| 2 | 931, 990, 116, 120, 634 |
| 2 | 931, 495, 58, 60, 317 |
| 3 | 931, 495, 29, 30, 317 |
| 5 | 931, 165, 29, 10, 317 |
| 931, 33, 29, 2, 317 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 931 x 33 x 29 x 2 x 317 = 33892384680
Therefore, the lowest common multiple of 931,990,116,120,634 is 33892384680.
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 990 x 116 x 120 x 634 = 8134172323200
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
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
116 : 1, 2, 4, 29, 58, 116
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
634 : 1, 2, 317, 634
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 931,990,116,120,634, is 1.
Now, the common factors can be found like this.
931:7x 7x 19
990:2x 3x 3x 5x 11
116:2x 2x 29
120:2x 2x 2x 3x 5
634:2x 317
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 2x 2x 3x 5 = 240
Therefore, the value for common factors is 240.
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 = 8134172323200/(1x240)
LCM = 8134172323200/240
LCM = 33892384680
Thus, we can understand that the LCM of 931,990,116,120,634 is 33892384680.
