Given numbers are 202,838,180,505
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 202,838,180,505 is 7617420.
Find LCM of 202,838,180,505 with Prime Factorization
| 2 | 202, 838, 180, 505 |
| 5 | 101, 419, 90, 505 |
| 101 | 101, 419, 18, 101 |
| 1, 419, 18, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 101 x 1 x 419 x 18 x 1 = 7617420
Therefore, the lowest common multiple of 202,838,180,505 is 7617420.
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.
202 x 838 x 180 x 505 = 15387188400
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.
202 : 1, 2, 101, 202
838 : 1, 2, 419, 838
180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180
505 : 1, 5, 101, 505
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 202,838,180,505, is 1.
Now, the common factors can be found like this.
202:2x 101
838:2x 419
180:2x 2x 3x 3x 5
505:5x 101
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 5x 101 = 2020
Therefore, the value for common factors is 2020.
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 = 15387188400/(1x2020)
LCM = 15387188400/2020
LCM = 7617420
Thus, we can understand that the LCM of 202,838,180,505 is 7617420.
