Given numbers are 4,784,209,308
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 4,784,209,308 is 163856.
Find LCM of 4,784,209,308 with Prime Factorization
2 | 4, 784, 209, 308 |
2 | 2, 392, 209, 154 |
7 | 1, 196, 209, 77 |
11 | 1, 28, 209, 11 |
1, 28, 19, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 11 x 1 x 28 x 19 x 1 = 163856
Therefore, the lowest common multiple of 4,784,209,308 is 163856.
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.
4 x 784 x 209 x 308 = 201870592
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.
4 : 1, 2, 4
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
209 : 1, 11, 19, 209
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 4,784,209,308, is 1.
Now, the common factors can be found like this.
4:2x 2
784:2x 2x 2x 2x 7x 7
209:11x 19
308:2x 2x 7x 11
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 2x 7x 11 = 1232
Therefore, the value for common factors is 1232.
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 = 201870592/(1x1232)
LCM = 201870592/1232
LCM = 163856
Thus, we can understand that the LCM of 4,784,209,308 is 163856.
