Given numbers are 431,126,781,923,253
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 431,126,781,923,253 is 12681482814.
Find LCM of 431,126,781,923,253 with Prime Factorization
| 11 | 431, 126, 781, 923, 253 |
| 71 | 431, 126, 71, 923, 23 |
| 431, 126, 1, 13, 23 |
Multiply the prime numbers at the bottom and the left side.
11 x 71 x 431 x 126 x 1 x 13 x 23 = 12681482814
Therefore, the lowest common multiple of 431,126,781,923,253 is 12681482814.
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.
431 x 126 x 781 x 923 x 253 = 9904238077734
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.
431 : 1, 431
126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126
781 : 1, 11, 71, 781
923 : 1, 13, 71, 923
253 : 1, 11, 23, 253
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 431,126,781,923,253, is 1.
Now, the common factors can be found like this.
431:431
126:2x 3x 3x 7
781:11x 71
923:13x 71
253:11x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 71 = 781
Therefore, the value for common factors is 781.
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 = 9904238077734/(1x781)
LCM = 9904238077734/781
LCM = 12681482814
Thus, we can understand that the LCM of 431,126,781,923,253 is 12681482814.
