The LCM of 828,161,874,764 is 21033684.
Find LCM of 828,161,874,764 with Prime Factorization
| 2 | 828, 161, 874, 764 |
| 2 | 414, 161, 437, 382 |
| 23 | 207, 161, 437, 191 |
| 9, 7, 19, 191 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 23 x 9 x 7 x 19 x 191 = 21033684
Therefore, the lowest common multiple of 828,161,874,764 is 21033684.
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.
828 x 161 x 874 x 764 = 89014550688
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.
828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828
161 : 1, 7, 23, 161
874 : 1, 2, 19, 23, 38, 46, 437, 874
764 : 1, 2, 4, 191, 382, 764
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 828,161,874,764, is 1.
Now, the common factors can be found like this.
828:2x 2x 3x 3x 23
161:7x 23
874:2x 19x 23
764:2x 2x 191
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 23x 23 = 4232
Therefore, the value for common factors is 4232.
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 = 89014550688/(1x4232)
LCM = 89014550688/4232
LCM = 21033684
Thus, we can understand that the LCM of 828,161,874,764 is 21033684.
