Given numbers are 554,665,644,672
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 554,665,644,672 is 406724640.
Find LCM of 554,665,644,672 with Prime Factorization
| 2 | 554, 665, 644, 672 |
| 2 | 277, 665, 322, 336 |
| 7 | 277, 665, 161, 168 |
| 277, 95, 23, 24 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 277 x 95 x 23 x 24 = 406724640
Therefore, the lowest common multiple of 554,665,644,672 is 406724640.
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.
554 x 665 x 644 x 672 = 159436058880
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.
554 : 1, 2, 277, 554
665 : 1, 5, 7, 19, 35, 95, 133, 665
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
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 554,665,644,672, is 1.
Now, the common factors can be found like this.
554:2x 277
665:5x 7x 19
644:2x 2x 7x 23
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 7x 7 = 392
Therefore, the value for common factors is 392.
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 = 159436058880/(1x392)
LCM = 159436058880/392
LCM = 406724640
Thus, we can understand that the LCM of 554,665,644,672 is 406724640.
