Given numbers are 432,428,747,246
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 432,428,747,246 is 157300272.
Find LCM of 432,428,747,246 with Prime Factorization
2 | 432, 428, 747, 246 |
2 | 216, 214, 747, 123 |
3 | 108, 107, 747, 123 |
3 | 36, 107, 249, 41 |
12, 107, 83, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 12 x 107 x 83 x 41 = 157300272
Therefore, the lowest common multiple of 432,428,747,246 is 157300272.
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.
432 x 428 x 747 x 246 = 33976858752
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.
432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432
428 : 1, 2, 4, 107, 214, 428
747 : 1, 3, 9, 83, 249, 747
246 : 1, 2, 3, 6, 41, 82, 123, 246
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 432,428,747,246, is 1.
Now, the common factors can be found like this.
432:2x 2x 2x 2x 3x 3x 3
428:2x 2x 107
747:3x 3x 83
246:2x 3x 41
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 2x 3x 3x 3 = 216
Therefore, the value for common factors is 216.
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 = 33976858752/(1x216)
LCM = 33976858752/216
LCM = 157300272
Thus, we can understand that the LCM of 432,428,747,246 is 157300272.
