The LCM of 693,385,958,902 is 136098270.
Find LCM of 693,385,958,902 with Prime Factorization
| 2 | 693, 385, 958, 902 |
| 7 | 693, 385, 479, 451 |
| 11 | 99, 55, 479, 451 |
| 9, 5, 479, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 11 x 9 x 5 x 479 x 41 = 136098270
Therefore, the lowest common multiple of 693,385,958,902 is 136098270.
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.
693 x 385 x 958 x 902 = 230550469380
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.
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
385 : 1, 5, 7, 11, 35, 55, 77, 385
958 : 1, 2, 479, 958
902 : 1, 2, 11, 22, 41, 82, 451, 902
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 693,385,958,902, is 1.
Now, the common factors can be found like this.
693:3x 3x 7x 11
385:5x 7x 11
958:2x 479
902:2x 11x 41
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 11x 11 = 1694
Therefore, the value for common factors is 1694.
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 = 230550469380/(1x1694)
LCM = 230550469380/1694
LCM = 136098270
Thus, we can understand that the LCM of 693,385,958,902 is 136098270.
