Given numbers are 686,917,475,931,324
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 686,917,475,931,324 is 6915188700.
Find LCM of 686,917,475,931,324 with Prime Factorization
| 2 | 686, 917, 475, 931, 324 |
| 7 | 343, 917, 475, 931, 162 |
| 7 | 49, 131, 475, 133, 162 |
| 19 | 7, 131, 475, 19, 162 |
| 7, 131, 25, 1, 162 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 7 x 19 x 7 x 131 x 25 x 1 x 162 = 6915188700
Therefore, the lowest common multiple of 686,917,475,931,324 is 6915188700.
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 917 x 475 x 931 x 324 = 90132569515800
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
917 : 1, 7, 131, 917
475 : 1, 5, 19, 25, 95, 475
931 : 1, 7, 19, 49, 133, 931
324 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 324
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 686,917,475,931,324, is 1.
Now, the common factors can be found like this.
686:2x 7x 7x 7
917:7x 131
475:5x 5x 19
931:7x 7x 19
324:2x 2x 3x 3x 3x 3
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 7x 7x 19 = 13034
Therefore, the value for common factors is 13034.
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 = 90132569515800/(1x13034)
LCM = 90132569515800/13034
LCM = 6915188700
Thus, we can understand that the LCM of 686,917,475,931,324 is 6915188700.
