Given numbers are 685,143,808,548
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 685,143,808,548 is 79147640.
Find LCM of 685,143,808,548 with Prime Factorization
| 2 | 685, 143, 808, 548 |
| 2 | 685, 143, 404, 274 |
| 137 | 685, 143, 202, 137 |
| 5, 143, 202, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 137 x 5 x 143 x 202 x 1 = 79147640
Therefore, the lowest common multiple of 685,143,808,548 is 79147640.
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.
685 x 143 x 808 x 548 = 43372906720
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.
685 : 1, 5, 137, 685
143 : 1, 11, 13, 143
808 : 1, 2, 4, 8, 101, 202, 404, 808
548 : 1, 2, 4, 137, 274, 548
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 685,143,808,548, is 1.
Now, the common factors can be found like this.
685:5x 137
143:11x 13
808:2x 2x 2x 101
548:2x 2x 137
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 137 = 548
Therefore, the value for common factors is 548.
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 = 43372906720/(1x548)
LCM = 43372906720/548
LCM = 79147640
Thus, we can understand that the LCM of 685,143,808,548 is 79147640.
