Find LCM of 681,742,879,140,252 with Prime Factorization
| 2 | 681, 742, 879, 140, 252 |
| 2 | 681, 371, 879, 70, 126 |
| 3 | 681, 371, 879, 35, 63 |
| 7 | 227, 371, 293, 35, 21 |
| 227, 53, 293, 5, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 227 x 53 x 293 x 5 x 3 = 4441604580
Therefore, the lowest common multiple of 681,742,879,140,252 is 4441604580.
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.
681 x 742 x 879 x 140 x 252 = 15669980958240
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.
681 : 1, 3, 227, 681
742 : 1, 2, 7, 14, 53, 106, 371, 742
879 : 1, 3, 293, 879
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 681,742,879,140,252, is 1.
Now, the common factors can be found like this.
681:3x 227
742:2x 7x 53
879:3x 293
140:2x 2x 5x 7
252:2x 2x 3x 3x 7
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 3x 3x 7x 7 = 3528
Therefore, the value for common factors is 3528.
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 = 15669980958240/(1x3528)
LCM = 15669980958240/3528
LCM = 4441604580
Thus, we can understand that the LCM of 681,742,879,140,252 is 4441604580.
