Find LCM of 611,868,104,987 with Prime Factorization
| 2 | 611, 868, 104, 987 |
| 2 | 611, 434, 52, 987 |
| 7 | 611, 217, 26, 987 |
| 13 | 611, 31, 26, 141 |
| 47 | 47, 31, 2, 141 |
| 1, 31, 2, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 13 x 47 x 1 x 31 x 2 x 3 = 3182088
Therefore, the lowest common multiple of 611,868,104,987 is 3182088.
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.
611 x 868 x 104 x 987 = 54439161504
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.
611 : 1, 13, 47, 611
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
104 : 1, 2, 4, 8, 13, 26, 52, 104
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 611,868,104,987, is 1.
Now, the common factors can be found like this.
611:13x 47
868:2x 2x 7x 31
104:2x 2x 2x 13
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 7x 13x 47 = 17108
Therefore, the value for common factors is 17108.
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 = 54439161504/(1x17108)
LCM = 54439161504/17108
LCM = 3182088
Thus, we can understand that the LCM of 611,868,104,987 is 3182088.
