Find LCM of 804,945,604,686 with Prime Factorization
2 | 804, 945, 604, 686 |
2 | 402, 945, 302, 343 |
3 | 201, 945, 151, 343 |
7 | 67, 315, 151, 343 |
67, 45, 151, 49 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 67 x 45 x 151 x 49 = 1873870740
Therefore, the lowest common multiple of 804,945,604,686 is 1873870740.
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.
804 x 945 x 604 x 686 = 314810284320
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.
804 : 1, 2, 3, 4, 6, 12, 67, 134, 201, 268, 402, 804
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
604 : 1, 2, 4, 151, 302, 604
686 : 1, 2, 7, 14, 49, 98, 343, 686
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 804,945,604,686, is 1.
Now, the common factors can be found like this.
804:2x 2x 3x 67
945:3x 3x 3x 5x 7
604:2x 2x 151
686:2x 7x 7x 7
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 3x 7 = 168
Therefore, the value for common factors is 168.
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 = 314810284320/(1x168)
LCM = 314810284320/168
LCM = 1873870740
Thus, we can understand that the LCM of 804,945,604,686 is 1873870740.
