Given numbers are 251,126,218,393
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 251,126,218,393 is 451587654.
Find LCM of 251,126,218,393 with Prime Factorization
| 2 | 251, 126, 218, 393 |
| 3 | 251, 63, 109, 393 |
| 251, 21, 109, 131 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 251 x 21 x 109 x 131 = 451587654
Therefore, the lowest common multiple of 251,126,218,393 is 451587654.
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.
251 x 126 x 218 x 393 = 2709525924
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.
251 : 1, 251
126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126
218 : 1, 2, 109, 218
393 : 1, 3, 131, 393
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 251,126,218,393, is 1.
Now, the common factors can be found like this.
251:251
126:2x 3x 3x 7
218:2x 109
393:3x 131
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 2709525924/(1x6)
LCM = 2709525924/6
LCM = 451587654
Thus, we can understand that the LCM of 251,126,218,393 is 451587654.
