Find LCM of 427,861,126,464,831 with Prime Factorization
2 | 427, 861, 126, 464, 831 |
3 | 427, 861, 63, 232, 831 |
7 | 427, 287, 21, 232, 277 |
61, 41, 3, 232, 277 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 61 x 41 x 3 x 232 x 277 = 20251257264
Therefore, the lowest common multiple of 427,861,126,464,831 is 20251257264.
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.
427 x 861 x 126 x 464 x 831 = 17861608906848
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.
427 : 1, 7, 61, 427
861 : 1, 3, 7, 21, 41, 123, 287, 861
126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126
464 : 1, 2, 4, 8, 16, 29, 58, 116, 232, 464
831 : 1, 3, 277, 831
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 427,861,126,464,831, is 1.
Now, the common factors can be found like this.
427:7x 61
861:3x 7x 41
126:2x 3x 3x 7
464:2x 2x 2x 2x 29
831:3x 277
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 7x 7 = 882
Therefore, the value for common factors is 882.
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 = 17861608906848/(1x882)
LCM = 17861608906848/882
LCM = 20251257264
Thus, we can understand that the LCM of 427,861,126,464,831 is 20251257264.
