Given numbers are 892,798,918,868
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 892,798,918,868 is 1688071644.
Find LCM of 892,798,918,868 with Prime Factorization
| 2 | 892, 798, 918, 868 |
| 2 | 446, 399, 459, 434 |
| 3 | 223, 399, 459, 217 |
| 7 | 223, 133, 153, 217 |
| 223, 19, 153, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 223 x 19 x 153 x 31 = 1688071644
Therefore, the lowest common multiple of 892,798,918,868 is 1688071644.
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.
892 x 798 x 918 x 868 = 567192072384
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.
892 : 1, 2, 4, 223, 446, 892
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 892,798,918,868, is 2.
Now, the common factors can be found like this.
892:2x 2x 223
798:2x 3x 7x 19
918:2x 3x 3x 3x 17
868:2x 2x 7x 31
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 7 = 168
Therefore, the value for common factors is 168.
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 = 567192072384/(2x168)
LCM = 567192072384/336
LCM = 1688071644
Thus, we can understand that the LCM of 892,798,918,868 is 1688071644.
