Find LCM of 120,714,789,441,386 with Prime Factorization
2 | 120, 714, 789, 441, 386 |
3 | 60, 357, 789, 441, 193 |
7 | 20, 119, 263, 147, 193 |
20, 17, 263, 21, 193 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 20 x 17 x 263 x 21 x 193 = 15221608920
Therefore, the lowest common multiple of 120,714,789,441,386 is 15221608920.
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.
120 x 714 x 789 x 441 x 386 = 11507536343520
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.
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
714 : 1, 2, 3, 6, 7, 14, 17, 21, 34, 42, 51, 102, 119, 238, 357, 714
789 : 1, 3, 263, 789
441 : 1, 3, 7, 9, 21, 49, 63, 147, 441
386 : 1, 2, 193, 386
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 120,714,789,441,386, is 1.
Now, the common factors can be found like this.
120:2x 2x 2x 3x 5
714:2x 3x 7x 17
789:3x 263
441:3x 3x 7x 7
386:2x 193
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 7 = 756
Therefore, the value for common factors is 756.
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 = 11507536343520/(1x756)
LCM = 11507536343520/756
LCM = 15221608920
Thus, we can understand that the LCM of 120,714,789,441,386 is 15221608920.
