Find LCM of 747,427,892,669,388 with Prime Factorization
| 2 | 747, 427, 892, 669, 388 |
| 2 | 747, 427, 446, 669, 194 |
| 3 | 747, 427, 223, 669, 97 |
| 223 | 249, 427, 223, 223, 97 |
| 249, 427, 1, 1, 97 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 223 x 249 x 427 x 1 x 1 x 97 = 27598473756
Therefore, the lowest common multiple of 747,427,892,669,388 is 27598473756.
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.
747 x 427 x 892 x 669 x 388 = 73853515771056
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.
747 : 1, 3, 9, 83, 249, 747
427 : 1, 7, 61, 427
892 : 1, 2, 4, 223, 446, 892
669 : 1, 3, 223, 669
388 : 1, 2, 4, 97, 194, 388
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 747,427,892,669,388, is 1.
Now, the common factors can be found like this.
747:3x 3x 83
427:7x 61
892:2x 2x 223
669:3x 223
388:2x 2x 97
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 223 = 2676
Therefore, the value for common factors is 2676.
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 = 73853515771056/(1x2676)
LCM = 73853515771056/2676
LCM = 27598473756
Thus, we can understand that the LCM of 747,427,892,669,388 is 27598473756.
