Given numbers are 588,400,646,200
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 588,400,646,200 is 18992400.
Find LCM of 588,400,646,200 with Prime Factorization
| 2 | 588, 400, 646, 200 |
| 2 | 294, 200, 323, 100 |
| 2 | 147, 50, 323, 100 |
| 5 | 147, 25, 323, 50 |
| 5 | 147, 5, 323, 10 |
| 147, 1, 323, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 5 x 147 x 1 x 323 x 2 = 18992400
Therefore, the lowest common multiple of 588,400,646,200 is 18992400.
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.
588 x 400 x 646 x 200 = 30387840000
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.
588 : 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 49, 84, 98, 147, 196, 294, 588
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
646 : 1, 2, 17, 19, 34, 38, 323, 646
200 : 1, 2, 4, 5, 8, 10, 20, 25, 40, 50, 100, 200
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 588,400,646,200, is 2.
Now, the common factors can be found like this.
588:2x 2x 3x 7x 7
400:2x 2x 2x 2x 5x 5
646:2x 17x 19
200:2x 2x 2x 5x 5
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 2x 5x 5 = 800
Therefore, the value for common factors is 800.
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 = 30387840000/(2x800)
LCM = 30387840000/1600
LCM = 18992400
Thus, we can understand that the LCM of 588,400,646,200 is 18992400.
