Given numbers are 9725,1820
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 9725,1820 is 3539900.
Find LCM of 9725,1820 with Prime Factorization
| 5 | 9725, 1820 |
| 1945, 364 |
Multiply the prime numbers at the bottom and the left side.
5 x 1945 x 364 = 3539900
Therefore, the lowest common multiple of 9725,1820 is 3539900.
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.
9725 x 1820 = 17699500
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.
9725 : 1, 5, 25, 389, 1945, 9725
1820 : 1, 2, 4, 5, 7, 10, 13, 14, 20, 26, 28, 35, 52, 65, 70, 91, 130, 140, 182, 260, 364, 455, 910, 1820
5 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 9725,1820, is 5.
Now, the common factors can be found like this.
9725:5x 5x 389
1820:2x 2x 5x 7x 13
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 = 17699500/(5x1)
LCM = 17699500/5
LCM = 3539900
Thus, we can understand that the LCM of 9725,1820 is 3539900.
