Find LCM of 702,897,122,300,720 with Prime Factorization
| 2 | 702, 897, 122, 300, 720 |
| 2 | 351, 897, 61, 150, 360 |
| 3 | 351, 897, 61, 75, 180 |
| 3 | 117, 299, 61, 25, 60 |
| 5 | 39, 299, 61, 25, 20 |
| 13 | 39, 299, 61, 5, 4 |
| 3, 23, 61, 5, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 13 x 3 x 23 x 61 x 5 x 4 = 196981200
Therefore, the lowest common multiple of 702,897,122,300,720 is 196981200.
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.
702 x 897 x 122 x 300 x 720 = 16593696288000
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.
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
897 : 1, 3, 13, 23, 39, 69, 299, 897
122 : 1, 2, 61, 122
300 : 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 25, 30, 50, 60, 75, 100, 150, 300
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 702,897,122,300,720, is 1.
Now, the common factors can be found like this.
702:2x 3x 3x 3x 13
897:3x 13x 23
122:2x 61
300:2x 2x 3x 5x 5
720:2x 2x 2x 2x 3x 3x 5
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 3x 3x 3x 3x 5x 13 = 84240
Therefore, the value for common factors is 84240.
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 = 16593696288000/(1x84240)
LCM = 16593696288000/84240
LCM = 196981200
Thus, we can understand that the LCM of 702,897,122,300,720 is 196981200.
