Given numbers are 626,217,168,804
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 626,217,168,804 is 109216968.
Find LCM of 626,217,168,804 with Prime Factorization
| 2 | 626, 217, 168, 804 |
| 2 | 313, 217, 84, 402 |
| 3 | 313, 217, 42, 201 |
| 7 | 313, 217, 14, 67 |
| 313, 31, 2, 67 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 313 x 31 x 2 x 67 = 109216968
Therefore, the lowest common multiple of 626,217,168,804 is 109216968.
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.
626 x 217 x 168 x 804 = 18348450624
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.
626 : 1, 2, 313, 626
217 : 1, 7, 31, 217
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
804 : 1, 2, 3, 4, 6, 12, 67, 134, 201, 268, 402, 804
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 626,217,168,804, is 1.
Now, the common factors can be found like this.
626:2x 313
217:7x 31
168:2x 2x 2x 3x 7
804:2x 2x 3x 67
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 2x 3x 7 = 168
Therefore, the value for common factors is 168.
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 = 18348450624/(1x168)
LCM = 18348450624/168
LCM = 109216968
Thus, we can understand that the LCM of 626,217,168,804 is 109216968.
