Find LCM of 693,770,808,320,931 with Prime Factorization
| 2 | 693, 770, 808, 320, 931 |
| 2 | 693, 385, 404, 160, 931 |
| 2 | 693, 385, 202, 80, 931 |
| 5 | 693, 385, 101, 40, 931 |
| 7 | 693, 77, 101, 8, 931 |
| 11 | 99, 11, 101, 8, 133 |
| 9, 1, 101, 8, 133 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 7 x 11 x 9 x 1 x 101 x 8 x 133 = 2978902080
Therefore, the lowest common multiple of 693,770,808,320,931 is 2978902080.
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 770 x 808 x 320 x 931 = 128450257689600
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
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
808 : 1, 2, 4, 8, 101, 202, 404, 808
320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320
931 : 1, 7, 19, 49, 133, 931
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 693,770,808,320,931, is 1.
Now, the common factors can be found like this.
693:3x 3x 7x 11
770:2x 5x 7x 11
808:2x 2x 2x 101
320:2x 2x 2x 2x 2x 2x 5
931:7x 7x 19
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 5x 7x 7x 11 = 43120
Therefore, the value for common factors is 43120.
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 = 128450257689600/(1x43120)
LCM = 128450257689600/43120
LCM = 2978902080
Thus, we can understand that the LCM of 693,770,808,320,931 is 2978902080.
