The LCM of 869,345,575,387,506 is 386748450.
Find LCM of 869,345,575,387,506 with Prime Factorization
| 3 | 869, 345, 575, 387, 506 |
| 5 | 869, 115, 575, 129, 506 |
| 11 | 869, 23, 115, 129, 506 |
| 23 | 79, 23, 115, 129, 46 |
| 79, 1, 5, 129, 2 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 11 x 23 x 79 x 1 x 5 x 129 x 2 = 386748450
Therefore, the lowest common multiple of 869,345,575,387,506 is 386748450.
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.
869 x 345 x 575 x 387 x 506 = 33757338458250
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.
869 : 1, 11, 79, 869
345 : 1, 3, 5, 15, 23, 69, 115, 345
575 : 1, 5, 23, 25, 115, 575
387 : 1, 3, 9, 43, 129, 387
506 : 1, 2, 11, 22, 23, 46, 253, 506
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 869,345,575,387,506, is 1.
Now, the common factors can be found like this.
869:11x 79
345:3x 5x 23
575:5x 5x 23
387:3x 3x 43
506:2x 11x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 11x 23x 23 = 87285
Therefore, the value for common factors is 87285.
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 = 33757338458250/(1x87285)
LCM = 33757338458250/87285
LCM = 386748450
Thus, we can understand that the LCM of 869,345,575,387,506 is 386748450.
