Given numbers are 1603,1764
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 1603,1764 is 403956.
Find LCM of 1603,1764 with Prime Factorization
| 7 | 1603, 1764 |
| 229, 252 |
Multiply the prime numbers at the bottom and the left side.
7 x 229 x 252 = 403956
Therefore, the lowest common multiple of 1603,1764 is 403956.
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.
1603 x 1764 = 2827692
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.
1603 : 1, 7, 229, 1603
1764 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 49, 63, 84, 98, 126, 147, 196, 252, 294, 441, 588, 882, 1764
7 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 1603,1764, is 7.
Now, the common factors can be found like this.
1603:7x 229
1764:2x 2x 3x 3x 7x 7
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 = 2827692/(7x1)
LCM = 2827692/7
LCM = 403956
Thus, we can understand that the LCM of 1603,1764 is 403956.
