Given numbers are 785,686,686,466,140
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 785,686,686,466,140 is 250945660.
Find LCM of 785,686,686,466,140 with Prime Factorization
| 2 | 785, 686, 686, 466, 140 |
| 5 | 785, 343, 343, 233, 70 |
| 7 | 157, 343, 343, 233, 14 |
| 7 | 157, 49, 49, 233, 2 |
| 7 | 157, 7, 7, 233, 2 |
| 157, 1, 1, 233, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 7 x 7 x 157 x 1 x 1 x 233 x 2 = 250945660
Therefore, the lowest common multiple of 785,686,686,466,140 is 250945660.
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.
785 x 686 x 686 x 466 x 140 = 24100821186400
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.
785 : 1, 5, 157, 785
686 : 1, 2, 7, 14, 49, 98, 343, 686
686 : 1, 2, 7, 14, 49, 98, 343, 686
466 : 1, 2, 233, 466
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 785,686,686,466,140, is 1.
Now, the common factors can be found like this.
785:5x 157
686:2x 7x 7x 7
686:2x 7x 7x 7
466:2x 233
140:2x 2x 5x 7
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 5x 7x 7x 7x 7 = 96040
Therefore, the value for common factors is 96040.
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 = 24100821186400/(1x96040)
LCM = 24100821186400/96040
LCM = 250945660
Thus, we can understand that the LCM of 785,686,686,466,140 is 250945660.
