Given numbers are 618,720,538,200
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 618,720,538,200 is 99745200.
Find LCM of 618,720,538,200 with Prime Factorization
| 2 | 618, 720, 538, 200 |
| 2 | 309, 360, 269, 100 |
| 2 | 309, 180, 269, 50 |
| 3 | 309, 90, 269, 25 |
| 5 | 103, 30, 269, 25 |
| 103, 6, 269, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 103 x 6 x 269 x 5 = 99745200
Therefore, the lowest common multiple of 618,720,538,200 is 99745200.
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.
618 x 720 x 538 x 200 = 47877696000
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.
618 : 1, 2, 3, 6, 103, 206, 309, 618
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
538 : 1, 2, 269, 538
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 618,720,538,200, is 2.
Now, the common factors can be found like this.
618:2x 3x 103
720:2x 2x 2x 2x 3x 3x 5
538:2x 269
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 3x 5 = 240
Therefore, the value for common factors is 240.
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 = 47877696000/(2x240)
LCM = 47877696000/480
LCM = 99745200
Thus, we can understand that the LCM of 618,720,538,200 is 99745200.
