Given numbers are 722,270,540
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 722,270,540 is 194940.
Find LCM of 722,270,540 with Prime Factorization
2 | 722, 270, 540 |
3 | 361, 135, 270 |
3 | 361, 45, 90 |
3 | 361, 15, 30 |
5 | 361, 5, 10 |
361, 1, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 5 x 361 x 1 x 2 = 194940
Therefore, the lowest common multiple of 722,270,540 is 194940.
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.
722 x 270 x 540 = 105267600
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.
722 : 1, 2, 19, 38, 361, 722
270 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 90, 135, 270
540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 722,270,540, is 2.
Now, the common factors can be found like this.
722:2x 19x 19
270:2x 3x 3x 3x 5
540:2x 2x 3x 3x 3x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 5 = 270
Therefore, the value for common factors is 270.
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 = 105267600/(2x270)
LCM = 105267600/540
LCM = 194940
Thus, we can understand that the LCM of 722,270,540 is 194940.
