Given numbers are 625,561,989,177
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 625,561,989,177 is 20459319375.
Find LCM of 625,561,989,177 with Prime Factorization
| 3 | 625, 561, 989, 177 |
| 625, 187, 989, 59 |
Multiply the prime numbers at the bottom and the left side.
3 x 625 x 187 x 989 x 59 = 20459319375
Therefore, the lowest common multiple of 625,561,989,177 is 20459319375.
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.
625 x 561 x 989 x 177 = 61377958125
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.
625 : 1, 5, 25, 125, 625
561 : 1, 3, 11, 17, 33, 51, 187, 561
989 : 1, 23, 43, 989
177 : 1, 3, 59, 177
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 625,561,989,177, is 1.
Now, the common factors can be found like this.
625:5x 5x 5x 5
561:3x 11x 17
989:23x 43
177:3x 59
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 61377958125/(1x3)
LCM = 61377958125/3
LCM = 20459319375
Thus, we can understand that the LCM of 625,561,989,177 is 20459319375.
