Find LCM of 722,682,412,378,861 with Prime Factorization
2 | 722, 682, 412, 378, 861 |
3 | 361, 341, 206, 189, 861 |
7 | 361, 341, 206, 63, 287 |
361, 341, 206, 9, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 361 x 341 x 206 x 9 x 41 = 393010775388
Therefore, the lowest common multiple of 722,682,412,378,861 is 393010775388.
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.
722 x 682 x 412 x 378 x 861 = 66025810265184
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.
722 : 1, 2, 19, 38, 361, 722
682 : 1, 2, 11, 22, 31, 62, 341, 682
412 : 1, 2, 4, 103, 206, 412
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
861 : 1, 3, 7, 21, 41, 123, 287, 861
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 722,682,412,378,861, is 1.
Now, the common factors can be found like this.
722:2x 19x 19
682:2x 11x 31
412:2x 2x 103
378:2x 3x 3x 3x 7
861:3x 7x 41
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 = 66025810265184/(1x168)
LCM = 66025810265184/168
LCM = 393010775388
Thus, we can understand that the LCM of 722,682,412,378,861 is 393010775388.
