Find LCM of 881,810,121,648 with Prime Factorization
2 | 881, 810, 121, 648 |
3 | 881, 405, 121, 324 |
3 | 881, 135, 121, 108 |
3 | 881, 45, 121, 36 |
3 | 881, 15, 121, 12 |
881, 5, 121, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 3 x 881 x 5 x 121 x 4 = 345387240
Therefore, the lowest common multiple of 881,810,121,648 is 345387240.
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.
881 x 810 x 121 x 648 = 55952732880
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.
881 : 1, 881
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
121 : 1, 11, 121
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 881,810,121,648, is 1.
Now, the common factors can be found like this.
881:881
810:2x 3x 3x 3x 3x 5
121:11x 11
648:2x 2x 2x 3x 3x 3x 3
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 3 = 162
Therefore, the value for common factors is 162.
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 = 55952732880/(1x162)
LCM = 55952732880/162
LCM = 345387240
Thus, we can understand that the LCM of 881,810,121,648 is 345387240.
