Given numbers are 5720,2120
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 5720,2120 is 303160.
Find LCM of 5720,2120 with Prime Factorization
| 2 | 5720, 2120 |
| 2 | 2860, 1060 |
| 2 | 1430, 530 |
| 5 | 715, 265 |
| 143, 53 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 143 x 53 = 303160
Therefore, the lowest common multiple of 5720,2120 is 303160.
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.
5720 x 2120 = 12126400
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.
5720 : 1, 2, 4, 5, 8, 10, 11, 13, 20, 22, 26, 40, 44, 52, 55, 65, 88, 104, 110, 130, 143, 220, 260, 286, 440, 520, 572, 715, 1144, 1430, 2860, 5720
2120 : 1, 2, 4, 5, 8, 10, 20, 40, 53, 106, 212, 265, 424, 530, 1060, 2120
40 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 5720,2120, is 40.
Now, the common factors can be found like this.
5720:2x 2x 2x 5x 11x 13
2120:2x 2x 2x 5x 53
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
= 1
Therefore, the value for common factors is 1.
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 = 12126400/(40x1)
LCM = 12126400/40
LCM = 303160
Thus, we can understand that the LCM of 5720,2120 is 303160.
