Given numbers are 646,434,252,662
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 646,434,252,662 is 835204356.
Find LCM of 646,434,252,662 with Prime Factorization
2 | 646, 434, 252, 662 |
7 | 323, 217, 126, 331 |
323, 31, 18, 331 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 323 x 31 x 18 x 331 = 835204356
Therefore, the lowest common multiple of 646,434,252,662 is 835204356.
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.
646 x 434 x 252 x 662 = 46771443936
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.
646 : 1, 2, 17, 19, 34, 38, 323, 646
434 : 1, 2, 7, 14, 31, 62, 217, 434
252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252
662 : 1, 2, 331, 662
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,434,252,662, is 2.
Now, the common factors can be found like this.
646:2x 17x 19
434:2x 7x 31
252:2x 2x 3x 3x 7
662:2x 331
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 7 = 28
Therefore, the value for common factors is 28.
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 = 46771443936/(2x28)
LCM = 46771443936/56
LCM = 835204356
Thus, we can understand that the LCM of 646,434,252,662 is 835204356.
