The LCM of 899,693,630,686 is 305273430.
Find LCM of 899,693,630,686 with Prime Factorization
| 2 | 899, 693, 630, 686 |
| 3 | 899, 693, 315, 343 |
| 3 | 899, 231, 105, 343 |
| 7 | 899, 77, 35, 343 |
| 899, 11, 5, 49 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 7 x 899 x 11 x 5 x 49 = 305273430
Therefore, the lowest common multiple of 899,693,630,686 is 305273430.
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.
899 x 693 x 630 x 686 = 269251165260
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.
899 : 1, 29, 31, 899
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630
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 899,693,630,686, is 1.
Now, the common factors can be found like this.
899:29x 31
693:3x 3x 7x 11
630:2x 3x 3x 5x 7
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 3x 3x 7x 7 = 882
Therefore, the value for common factors is 882.
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 = 269251165260/(1x882)
LCM = 269251165260/882
LCM = 305273430
Thus, we can understand that the LCM of 899,693,630,686 is 305273430.
