Given numbers are 475,703,784,198
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 475,703,784,198 is 1364101200.
Find LCM of 475,703,784,198 with Prime Factorization
| 2 | 475, 703, 784, 198 |
| 19 | 475, 703, 392, 99 |
| 25, 37, 392, 99 |
Multiply the prime numbers at the bottom and the left side.
2 x 19 x 25 x 37 x 392 x 99 = 1364101200
Therefore, the lowest common multiple of 475,703,784,198 is 1364101200.
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.
475 x 703 x 784 x 198 = 51835845600
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.
475 : 1, 5, 19, 25, 95, 475
703 : 1, 19, 37, 703
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 475,703,784,198, is 1.
Now, the common factors can be found like this.
475:5x 5x 19
703:19x 37
784:2x 2x 2x 2x 7x 7
198:2x 3x 3x 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 19 = 38
Therefore, the value for common factors is 38.
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 = 51835845600/(1x38)
LCM = 51835845600/38
LCM = 1364101200
Thus, we can understand that the LCM of 475,703,784,198 is 1364101200.
