Find LCM of 742,987,611,806,930 with Prime Factorization
| 2 | 742, 987, 611, 806, 930 |
| 3 | 371, 987, 611, 403, 465 |
| 7 | 371, 329, 611, 403, 155 |
| 13 | 53, 47, 611, 403, 155 |
| 31 | 53, 47, 47, 31, 155 |
| 47 | 53, 47, 47, 1, 5 |
| 53, 1, 1, 1, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 13 x 31 x 47 x 53 x 1 x 1 x 1 x 5 = 210813330
Therefore, the lowest common multiple of 742,987,611,806,930 is 210813330.
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.
742 x 987 x 611 x 806 x 930 = 335413283816520
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.
742 : 1, 2, 7, 14, 53, 106, 371, 742
987 : 1, 3, 7, 21, 47, 141, 329, 987
611 : 1, 13, 47, 611
806 : 1, 2, 13, 26, 31, 62, 403, 806
930 : 1, 2, 3, 5, 6, 10, 15, 30, 31, 62, 93, 155, 186, 310, 465, 930
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 742,987,611,806,930, is 1.
Now, the common factors can be found like this.
742:2x 7x 53
987:3x 7x 47
611:13x 47
806:2x 13x 31
930:2x 3x 5x 31
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 13x 31x 47 = 1591044
Therefore, the value for common factors is 1591044.
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 = 335413283816520/(1x1591044)
LCM = 335413283816520/1591044
LCM = 210813330
Thus, we can understand that the LCM of 742,987,611,806,930 is 210813330.
