Given numbers are 1098,5490
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 1098,5490 is 5490.
Find LCM of 1098,5490 with Prime Factorization
| 2 | 1098, 5490 |
| 3 | 549, 2745 |
| 3 | 183, 915 |
| 61 | 61, 305 |
| 1, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 61 x 1 x 5 = 5490
Therefore, the lowest common multiple of 1098,5490 is 5490.
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.
1098 x 5490 = 6028020
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.
1098 : 1, 2, 3, 6, 9, 18, 61, 122, 183, 366, 549, 1098
5490 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 61, 90, 122, 183, 305, 366, 549, 610, 915, 1098, 1830, 2745, 5490
1098 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 1098,5490, is 1098.
Now, the common factors can be found like this.
1098:2x 3x 3x 61
5490:2x 3x 3x 5x 61
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 = 6028020/(1098x1)
LCM = 6028020/1098
LCM = 5490
Thus, we can understand that the LCM of 1098,5490 is 5490.
