Given numbers are 621,990,442,525
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 621,990,442,525 is 528377850.
Find LCM of 621,990,442,525 with Prime Factorization
2 | 621, 990, 442, 525 |
3 | 621, 495, 221, 525 |
3 | 207, 165, 221, 175 |
5 | 69, 55, 221, 175 |
69, 11, 221, 35 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 69 x 11 x 221 x 35 = 528377850
Therefore, the lowest common multiple of 621,990,442,525 is 528377850.
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.
621 x 990 x 442 x 525 = 142662019500
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.
621 : 1, 3, 9, 23, 27, 69, 207, 621
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
442 : 1, 2, 13, 17, 26, 34, 221, 442
525 : 1, 3, 5, 7, 15, 21, 25, 35, 75, 105, 175, 525
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 621,990,442,525, is 1.
Now, the common factors can be found like this.
621:3x 3x 3x 23
990:2x 3x 3x 5x 11
442:2x 13x 17
525:3x 5x 5x 7
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 = 142662019500/(1x270)
LCM = 142662019500/270
LCM = 528377850
Thus, we can understand that the LCM of 621,990,442,525 is 528377850.
