Given numbers are 909,175,900,693
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 909,175,900,693 is 6999300.
Find LCM of 909,175,900,693 with Prime Factorization
| 3 | 909, 175, 900, 693 |
| 3 | 303, 175, 300, 231 |
| 5 | 101, 175, 100, 77 |
| 5 | 101, 35, 20, 77 |
| 7 | 101, 7, 4, 77 |
| 101, 1, 4, 11 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 5 x 7 x 101 x 1 x 4 x 11 = 6999300
Therefore, the lowest common multiple of 909,175,900,693 is 6999300.
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.
909 x 175 x 900 x 693 = 99215077500
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.
909 : 1, 3, 9, 101, 303, 909
175 : 1, 5, 7, 25, 35, 175
900 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 25, 30, 36, 45, 50, 60, 75, 90, 100, 150, 180, 225, 300, 450, 900
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 909,175,900,693, is 1.
Now, the common factors can be found like this.
909:3x 3x 101
175:5x 5x 7
900:2x 2x 3x 3x 5x 5
693:3x 3x 7x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 3x 5x 5x 7 = 14175
Therefore, the value for common factors is 14175.
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 = 99215077500/(1x14175)
LCM = 99215077500/14175
LCM = 6999300
Thus, we can understand that the LCM of 909,175,900,693 is 6999300.
