Given numbers are 808,785,686,922,628
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 808,785,686,922,628 is 100294256440.
Find LCM of 808,785,686,922,628 with Prime Factorization
| 2 | 808, 785, 686, 922, 628 |
| 2 | 404, 785, 343, 461, 314 |
| 157 | 202, 785, 343, 461, 157 |
| 202, 5, 343, 461, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 157 x 202 x 5 x 343 x 461 x 1 = 100294256440
Therefore, the lowest common multiple of 808,785,686,922,628 is 100294256440.
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.
808 x 785 x 686 x 922 x 628 = 251939172177280
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.
808 : 1, 2, 4, 8, 101, 202, 404, 808
785 : 1, 5, 157, 785
686 : 1, 2, 7, 14, 49, 98, 343, 686
922 : 1, 2, 461, 922
628 : 1, 2, 4, 157, 314, 628
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 808,785,686,922,628, is 1.
Now, the common factors can be found like this.
808:2x 2x 2x 101
785:5x 157
686:2x 7x 7x 7
922:2x 461
628:2x 2x 157
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 2x 2x 157 = 2512
Therefore, the value for common factors is 2512.
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 = 251939172177280/(1x2512)
LCM = 251939172177280/2512
LCM = 100294256440
Thus, we can understand that the LCM of 808,785,686,922,628 is 100294256440.
