Given numbers are 869,620,695,687,510
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 869,620,695,687,510 is 874645215180.
Find LCM of 869,620,695,687,510 with Prime Factorization
| 2 | 869, 620, 695, 687, 510 |
| 3 | 869, 310, 695, 687, 255 |
| 5 | 869, 310, 695, 229, 85 |
| 869, 62, 139, 229, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 869 x 62 x 139 x 229 x 17 = 874645215180
Therefore, the lowest common multiple of 869,620,695,687,510 is 874645215180.
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 620 x 695 x 687 x 510 = 131196782277000
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
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
695 : 1, 5, 139, 695
687 : 1, 3, 229, 687
510 : 1, 2, 3, 5, 6, 10, 15, 17, 30, 34, 51, 85, 102, 170, 255, 510
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 869,620,695,687,510, is 1.
Now, the common factors can be found like this.
869:11x 79
620:2x 2x 5x 31
695:5x 139
687:3x 229
510:2x 3x 5x 17
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 5x 5 = 150
Therefore, the value for common factors is 150.
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 = 131196782277000/(1x150)
LCM = 131196782277000/150
LCM = 874645215180
Thus, we can understand that the LCM of 869,620,695,687,510 is 874645215180.
