Given numbers are 653,635,161,441
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 653,635,161,441 is 4205845665.
Find LCM of 653,635,161,441 with Prime Factorization
| 7 | 653, 635, 161, 441 |
| 653, 635, 23, 63 |
Multiply the prime numbers at the bottom and the left side.
7 x 653 x 635 x 23 x 63 = 4205845665
Therefore, the lowest common multiple of 653,635,161,441 is 4205845665.
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.
653 x 635 x 161 x 441 = 29440919655
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.
653 : 1, 653
635 : 1, 5, 127, 635
161 : 1, 7, 23, 161
441 : 1, 3, 7, 9, 21, 49, 63, 147, 441
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 653,635,161,441, is 1.
Now, the common factors can be found like this.
653:653
635:5x 127
161:7x 23
441:3x 3x 7x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7 = 7
Therefore, the value for common factors is 7.
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 = 29440919655/(1x7)
LCM = 29440919655/7
LCM = 4205845665
Thus, we can understand that the LCM of 653,635,161,441 is 4205845665.
