Given numbers are 985,501,501,561
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 985,501,501,561 is 92281695.
Find LCM of 985,501,501,561 with Prime Factorization
| 3 | 985, 501, 501, 561 |
| 167 | 985, 167, 167, 187 |
| 985, 1, 1, 187 |
Multiply the prime numbers at the bottom and the left side.
3 x 167 x 985 x 1 x 1 x 187 = 92281695
Therefore, the lowest common multiple of 985,501,501,561 is 92281695.
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.
985 x 501 x 501 x 561 = 138699387585
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.
985 : 1, 5, 197, 985
501 : 1, 3, 167, 501
501 : 1, 3, 167, 501
561 : 1, 3, 11, 17, 33, 51, 187, 561
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 985,501,501,561, is 1.
Now, the common factors can be found like this.
985:5x 197
501:3x 167
501:3x 167
561:3x 11x 17
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 167 = 1503
Therefore, the value for common factors is 1503.
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 = 138699387585/(1x1503)
LCM = 138699387585/1503
LCM = 92281695
Thus, we can understand that the LCM of 985,501,501,561 is 92281695.
