Given numbers are 9920,4929
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 9920,4929 is 1577280.
Find LCM of 9920,4929 with Prime Factorization
| 31 | 9920, 4929 |
| 320, 159 |
Multiply the prime numbers at the bottom and the left side.
31 x 320 x 159 = 1577280
Therefore, the lowest common multiple of 9920,4929 is 1577280.
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.
9920 x 4929 = 48895680
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.
9920 : 1, 2, 4, 5, 8, 10, 16, 20, 31, 32, 40, 62, 64, 80, 124, 155, 160, 248, 310, 320, 496, 620, 992, 1240, 1984, 2480, 4960, 9920
4929 : 1, 3, 31, 53, 93, 159, 1643, 4929
31 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 9920,4929, is 31.
Now, the common factors can be found like this.
9920:2x 2x 2x 2x 2x 2x 5x 31
4929:3x 31x 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 = 48895680/(31x1)
LCM = 48895680/31
LCM = 1577280
Thus, we can understand that the LCM of 9920,4929 is 1577280.
