Given numbers are 678,168,875,126,241
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 678,168,875,126,241 is 1715679000.
Find LCM of 678,168,875,126,241 with Prime Factorization
| 2 | 678, 168, 875, 126, 241 |
| 3 | 339, 84, 875, 63, 241 |
| 7 | 113, 28, 875, 21, 241 |
| 113, 4, 125, 3, 241 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 113 x 4 x 125 x 3 x 241 = 1715679000
Therefore, the lowest common multiple of 678,168,875,126,241 is 1715679000.
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.
678 x 168 x 875 x 126 x 241 = 3026457756000
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.
678 : 1, 2, 3, 6, 113, 226, 339, 678
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
875 : 1, 5, 7, 25, 35, 125, 175, 875
126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126
241 : 1, 241
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 678,168,875,126,241, is 1.
Now, the common factors can be found like this.
678:2x 3x 113
168:2x 2x 2x 3x 7
875:5x 5x 5x 7
126:2x 3x 3x 7
241:241
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 3x 3x 7x 7 = 1764
Therefore, the value for common factors is 1764.
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 = 3026457756000/(1x1764)
LCM = 3026457756000/1764
LCM = 1715679000
Thus, we can understand that the LCM of 678,168,875,126,241 is 1715679000.
