Find LCM of 964,686,644,723,387 with Prime Factorization
2 | 964, 686, 644, 723, 387 |
2 | 482, 343, 322, 723, 387 |
3 | 241, 343, 161, 723, 387 |
7 | 241, 343, 161, 241, 129 |
241 | 241, 49, 23, 241, 129 |
1, 49, 23, 1, 129 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 241 x 1 x 49 x 23 x 1 x 129 = 2943133452
Therefore, the lowest common multiple of 964,686,644,723,387 is 2943133452.
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.
964 x 686 x 644 x 723 x 387 = 119161587204576
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.
964 : 1, 2, 4, 241, 482, 964
686 : 1, 2, 7, 14, 49, 98, 343, 686
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
723 : 1, 3, 241, 723
387 : 1, 3, 9, 43, 129, 387
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 964,686,644,723,387, is 1.
Now, the common factors can be found like this.
964:2x 2x 241
686:2x 7x 7x 7
644:2x 2x 7x 23
723:3x 241
387:3x 3x 43
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 7x 241 = 40488
Therefore, the value for common factors is 40488.
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 = 119161587204576/(1x40488)
LCM = 119161587204576/40488
LCM = 2943133452
Thus, we can understand that the LCM of 964,686,644,723,387 is 2943133452.
