The LCM of 228,702,702,661 is 17632836.
Find LCM of 228,702,702,661 with Prime Factorization
| 2 | 228, 702, 702, 661 |
| 3 | 114, 351, 351, 661 |
| 3 | 38, 117, 117, 661 |
| 3 | 38, 39, 39, 661 |
| 13 | 38, 13, 13, 661 |
| 38, 1, 1, 661 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 13 x 38 x 1 x 1 x 661 = 17632836
Therefore, the lowest common multiple of 228,702,702,661 is 17632836.
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.
228 x 702 x 702 x 661 = 74269505232
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.
228 : 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, 228
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
661 : 1, 661
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 228,702,702,661, is 1.
Now, the common factors can be found like this.
228:2x 2x 3x 19
702:2x 3x 3x 3x 13
702:2x 3x 3x 3x 13
661:661
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 3x 3x 3x 13 = 4212
Therefore, the value for common factors is 4212.
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 = 74269505232/(1x4212)
LCM = 74269505232/4212
LCM = 17632836
Thus, we can understand that the LCM of 228,702,702,661 is 17632836.
