Find LCM of 210,918,595,686 with Prime Factorization
| 2 | 210, 918, 595, 686 |
| 3 | 105, 459, 595, 343 |
| 5 | 35, 153, 595, 343 |
| 7 | 7, 153, 119, 343 |
| 17 | 1, 153, 17, 49 |
| 1, 9, 1, 49 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 17 x 1 x 9 x 1 x 49 = 1574370
Therefore, the lowest common multiple of 210,918,595,686 is 1574370.
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.
210 x 918 x 595 x 686 = 78687012600
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.
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
595 : 1, 5, 7, 17, 35, 85, 119, 595
686 : 1, 2, 7, 14, 49, 98, 343, 686
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 210,918,595,686, is 1.
Now, the common factors can be found like this.
210:2x 3x 5x 7
918:2x 3x 3x 3x 17
595:5x 7x 17
686:2x 7x 7x 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 3x 5x 7x 7x 17 = 49980
Therefore, the value for common factors is 49980.
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 = 78687012600/(1x49980)
LCM = 78687012600/49980
LCM = 1574370
Thus, we can understand that the LCM of 210,918,595,686 is 1574370.
