Given numbers are 684,889,902,672
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 684,889,902,672 is 2193938208.
Find LCM of 684,889,902,672 with Prime Factorization
| 2 | 684, 889, 902, 672 |
| 2 | 342, 889, 451, 336 |
| 3 | 171, 889, 451, 168 |
| 7 | 57, 889, 451, 56 |
| 57, 127, 451, 8 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 57 x 127 x 451 x 8 = 2193938208
Therefore, the lowest common multiple of 684,889,902,672 is 2193938208.
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.
684 x 889 x 902 x 672 = 368581618944
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.
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
889 : 1, 7, 127, 889
902 : 1, 2, 11, 22, 41, 82, 451, 902
672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 684,889,902,672, is 1.
Now, the common factors can be found like this.
684:2x 2x 3x 3x 19
889:7x 127
902:2x 11x 41
672:2x 2x 2x 2x 2x 3x 7
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 = 368581618944/(1x168)
LCM = 368581618944/168
LCM = 2193938208
Thus, we can understand that the LCM of 684,889,902,672 is 2193938208.
