The LCM of 621,575,135,834 is 4315950.
Find LCM of 621,575,135,834 with Prime Factorization
3 | 621, 575, 135, 834 |
3 | 207, 575, 45, 278 |
3 | 69, 575, 15, 278 |
5 | 23, 575, 5, 278 |
23 | 23, 115, 1, 278 |
1, 5, 1, 278 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 3 x 5 x 23 x 1 x 5 x 1 x 278 = 4315950
Therefore, the lowest common multiple of 621,575,135,834 is 4315950.
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 575 x 135 x 834 = 40203074250
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
575 : 1, 5, 23, 25, 115, 575
135 : 1, 3, 5, 9, 15, 27, 45, 135
834 : 1, 2, 3, 6, 139, 278, 417, 834
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 621,575,135,834, is 1.
Now, the common factors can be found like this.
621:3x 3x 3x 23
575:5x 5x 23
135:3x 3x 3x 5
834:2x 3x 139
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 3x 5x 23 = 9315
Therefore, the value for common factors is 9315.
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 = 40203074250/(1x9315)
LCM = 40203074250/9315
LCM = 4315950
Thus, we can understand that the LCM of 621,575,135,834 is 4315950.
