Given numbers are 622,148,169,126,561
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 622,148,169,126,561 is 91641241692.
Find LCM of 622,148,169,126,561 with Prime Factorization
| 2 | 622, 148, 169, 126, 561 |
| 3 | 311, 74, 169, 63, 561 |
| 311, 74, 169, 21, 187 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 311 x 74 x 169 x 21 x 187 = 91641241692
Therefore, the lowest common multiple of 622,148,169,126,561 is 91641241692.
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.
622 x 148 x 169 x 126 x 561 = 1099694900304
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.
622 : 1, 2, 311, 622
148 : 1, 2, 4, 37, 74, 148
169 : 1, 13, 169
126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126
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 622,148,169,126,561, is 1.
Now, the common factors can be found like this.
622:2x 311
148:2x 2x 37
169:13x 13
126:2x 3x 3x 7
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.
2x 2x 3 = 12
Therefore, the value for common factors is 12.
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 = 1099694900304/(1x12)
LCM = 1099694900304/12
LCM = 91641241692
Thus, we can understand that the LCM of 622,148,169,126,561 is 91641241692.
