Find LCM of 711,378,945,394 with Prime Factorization
2 | 711, 378, 945, 394 |
3 | 711, 189, 945, 197 |
3 | 237, 63, 315, 197 |
3 | 79, 21, 105, 197 |
7 | 79, 7, 35, 197 |
79, 1, 5, 197 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 7 x 79 x 1 x 5 x 197 = 29414070
Therefore, the lowest common multiple of 711,378,945,394 is 29414070.
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.
711 x 378 x 945 x 394 = 100066666140
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.
711 : 1, 3, 9, 79, 237, 711
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
394 : 1, 2, 197, 394
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 711,378,945,394, is 1.
Now, the common factors can be found like this.
711:3x 3x 79
378:2x 3x 3x 3x 7
945:3x 3x 3x 5x 7
394:2x 197
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 3x 3x 7 = 3402
Therefore, the value for common factors is 3402.
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 = 100066666140/(1x3402)
LCM = 100066666140/3402
LCM = 29414070
Thus, we can understand that the LCM of 711,378,945,394 is 29414070.
