Find LCM of 540,441,147,173,921 with Prime Factorization
3 | 540, 441, 147, 173, 921 |
3 | 180, 147, 49, 173, 307 |
7 | 60, 49, 49, 173, 307 |
7 | 60, 7, 7, 173, 307 |
60, 1, 1, 173, 307 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 7 x 7 x 60 x 1 x 1 x 173 x 307 = 1405317060
Therefore, the lowest common multiple of 540,441,147,173,921 is 1405317060.
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.
540 x 441 x 147 x 173 x 921 = 5577703411140
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.
540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540
441 : 1, 3, 7, 9, 21, 49, 63, 147, 441
147 : 1, 3, 7, 21, 49, 147
173 : 1, 173
921 : 1, 3, 307, 921
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 540,441,147,173,921, is 1.
Now, the common factors can be found like this.
540:2x 2x 3x 3x 3x 5
441:3x 3x 7x 7
147:3x 7x 7
173:173
921:3x 307
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 3x 7x 7 = 3969
Therefore, the value for common factors is 3969.
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 = 5577703411140/(1x3969)
LCM = 5577703411140/3969
LCM = 1405317060
Thus, we can understand that the LCM of 540,441,147,173,921 is 1405317060.
