Given numbers are 7146,4770
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 7146,4770 is 1893690.
Find LCM of 7146,4770 with Prime Factorization
| 2 | 7146, 4770 |
| 3 | 3573, 2385 |
| 3 | 1191, 795 |
| 397, 265 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 397 x 265 = 1893690
Therefore, the lowest common multiple of 7146,4770 is 1893690.
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.
7146 x 4770 = 34086420
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.
7146 : 1, 2, 3, 6, 9, 18, 397, 794, 1191, 2382, 3573, 7146
4770 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 53, 90, 106, 159, 265, 318, 477, 530, 795, 954, 1590, 2385, 4770
18 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 7146,4770, is 18.
Now, the common factors can be found like this.
7146:2x 3x 3x 397
4770:2x 3x 3x 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 = 34086420/(18x1)
LCM = 34086420/18
LCM = 1893690
Thus, we can understand that the LCM of 7146,4770 is 1893690.
