Given numbers are 901,989,816,612
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 901,989,816,612 is 128316816.
Find LCM of 901,989,816,612 with Prime Factorization
| 2 | 901, 989, 816, 612 |
| 2 | 901, 989, 408, 306 |
| 3 | 901, 989, 204, 153 |
| 17 | 901, 989, 68, 51 |
| 53, 989, 4, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 17 x 53 x 989 x 4 x 3 = 128316816
Therefore, the lowest common multiple of 901,989,816,612 is 128316816.
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.
901 x 989 x 816 x 612 = 445002717888
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.
901 : 1, 17, 53, 901
989 : 1, 23, 43, 989
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
612 : 1, 2, 3, 4, 6, 9, 12, 17, 18, 34, 36, 51, 68, 102, 153, 204, 306, 612
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 901,989,816,612, is 1.
Now, the common factors can be found like this.
901:17x 53
989:23x 43
816:2x 2x 2x 2x 3x 17
612:2x 2x 3x 3x 17
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 17x 17 = 3468
Therefore, the value for common factors is 3468.
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 = 445002717888/(1x3468)
LCM = 445002717888/3468
LCM = 128316816
Thus, we can understand that the LCM of 901,989,816,612 is 128316816.
