Given numbers are 782,529,969,431
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 782,529,969,431 is 441862062.
Find LCM of 782,529,969,431 with Prime Factorization
| 17 | 782, 529, 969, 431 |
| 23 | 46, 529, 57, 431 |
| 2, 23, 57, 431 |
Multiply the prime numbers at the bottom and the left side.
17 x 23 x 2 x 23 x 57 x 431 = 441862062
Therefore, the lowest common multiple of 782,529,969,431 is 441862062.
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.
782 x 529 x 969 x 431 = 172768066242
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.
782 : 1, 2, 17, 23, 34, 46, 391, 782
529 : 1, 23, 529
969 : 1, 3, 17, 19, 51, 57, 323, 969
431 : 1, 431
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 782,529,969,431, is 1.
Now, the common factors can be found like this.
782:2x 17x 23
529:23x 23
969:3x 17x 19
431:431
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
17x 23 = 391
Therefore, the value for common factors is 391.
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 = 172768066242/(1x391)
LCM = 172768066242/391
LCM = 441862062
Thus, we can understand that the LCM of 782,529,969,431 is 441862062.
