The LCM of 909,966,140,621 is 8780940.
Find LCM of 909,966,140,621 with Prime Factorization
| 2 | 909, 966, 140, 621 |
| 3 | 909, 483, 70, 621 |
| 3 | 303, 161, 70, 207 |
| 7 | 101, 161, 70, 69 |
| 23 | 101, 23, 10, 69 |
| 101, 1, 10, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 7 x 23 x 101 x 1 x 10 x 3 = 8780940
Therefore, the lowest common multiple of 909,966,140,621 is 8780940.
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 966 x 140 x 621 = 76341492360
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
966 : 1, 2, 3, 6, 7, 14, 21, 23, 42, 46, 69, 138, 161, 322, 483, 966
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
621 : 1, 3, 9, 23, 27, 69, 207, 621
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 909,966,140,621, is 1.
Now, the common factors can be found like this.
909:3x 3x 101
966:2x 3x 7x 23
140:2x 2x 5x 7
621:3x 3x 3x 23
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 3x 7x 23 = 8694
Therefore, the value for common factors is 8694.
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 = 76341492360/(1x8694)
LCM = 76341492360/8694
LCM = 8780940
Thus, we can understand that the LCM of 909,966,140,621 is 8780940.
