Given numbers are 721,618,271
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 721,618,271 is 1172346.
Find LCM of 721,618,271 with Prime Factorization
| 103 | 721, 618, 271 |
| 7, 6, 271 |
Multiply the prime numbers at the bottom and the left side.
103 x 7 x 6 x 271 = 1172346
Therefore, the lowest common multiple of 721,618,271 is 1172346.
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.
721 x 618 x 271 = 120751638
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.
721 : 1, 7, 103, 721
618 : 1, 2, 3, 6, 103, 206, 309, 618
271 : 1, 271
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,618,271, is 1.
Now, the common factors can be found like this.
721:7x 103
618:2x 3x 103
271:271
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
103 = 103
Therefore, the value for common factors is 103.
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 = 120751638/(1x103)
LCM = 120751638/103
LCM = 1172346
Thus, we can understand that the LCM of 721,618,271 is 1172346.
