The LCM of 762,756,216,121 is 23234904.
Find LCM of 762,756,216,121 with Prime Factorization
| 2 | 762, 756, 216, 121 |
| 2 | 381, 378, 108, 121 |
| 3 | 381, 189, 54, 121 |
| 3 | 127, 63, 18, 121 |
| 3 | 127, 21, 6, 121 |
| 127, 7, 2, 121 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 3 x 127 x 7 x 2 x 121 = 23234904
Therefore, the lowest common multiple of 762,756,216,121 is 23234904.
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.
762 x 756 x 216 x 121 = 15056217792
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.
762 : 1, 2, 3, 6, 127, 254, 381, 762
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
216 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 108, 216
121 : 1, 11, 121
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 762,756,216,121, is 1.
Now, the common factors can be found like this.
762:2x 3x 127
756:2x 2x 3x 3x 3x 7
216:2x 2x 2x 3x 3x 3
121:11x 11
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 3x 3 = 648
Therefore, the value for common factors is 648.
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 = 15056217792/(1x648)
LCM = 15056217792/648
LCM = 23234904
Thus, we can understand that the LCM of 762,756,216,121 is 23234904.
