Find LCM of 945,438,865,828,250 with Prime Factorization
| 2 | 945, 438, 865, 828, 250 |
| 3 | 945, 219, 865, 414, 125 |
| 3 | 315, 73, 865, 138, 125 |
| 5 | 105, 73, 865, 46, 125 |
| 21, 73, 173, 46, 25 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 21 x 73 x 173 x 46 x 25 = 27449131500
Therefore, the lowest common multiple of 945,438,865,828,250 is 27449131500.
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.
945 x 438 x 865 x 828 x 250 = 74112655050000
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.
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
438 : 1, 2, 3, 6, 73, 146, 219, 438
865 : 1, 5, 173, 865
828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828
250 : 1, 2, 5, 10, 25, 50, 125, 250
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 945,438,865,828,250, is 1.
Now, the common factors can be found like this.
945:3x 3x 3x 5x 7
438:2x 3x 73
865:5x 173
828:2x 2x 3x 3x 23
250:2x 5x 5x 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 3x 3x 3x 5x 5 = 2700
Therefore, the value for common factors is 2700.
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 = 74112655050000/(1x2700)
LCM = 74112655050000/2700
LCM = 27449131500
Thus, we can understand that the LCM of 945,438,865,828,250 is 27449131500.
