Given numbers are 686,600,505,604,774
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 686,600,505,604,774 is 404886598200.
Find LCM of 686,600,505,604,774 with Prime Factorization
| 2 | 686, 600, 505, 604, 774 |
| 2 | 343, 300, 505, 302, 387 |
| 3 | 343, 150, 505, 151, 387 |
| 5 | 343, 50, 505, 151, 129 |
| 343, 10, 101, 151, 129 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 343 x 10 x 101 x 151 x 129 = 404886598200
Therefore, the lowest common multiple of 686,600,505,604,774 is 404886598200.
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.
686 x 600 x 505 x 604 x 774 = 97172783568000
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.
686 : 1, 2, 7, 14, 49, 98, 343, 686
600 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 25, 30, 40, 50, 60, 75, 100, 120, 150, 200, 300, 600
505 : 1, 5, 101, 505
604 : 1, 2, 4, 151, 302, 604
774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 686,600,505,604,774, is 1.
Now, the common factors can be found like this.
686:2x 7x 7x 7
600:2x 2x 2x 3x 5x 5
505:5x 101
604:2x 2x 151
774:2x 3x 3x 43
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 3x 5 = 240
Therefore, the value for common factors is 240.
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 = 97172783568000/(1x240)
LCM = 97172783568000/240
LCM = 404886598200
Thus, we can understand that the LCM of 686,600,505,604,774 is 404886598200.
