Find LCM of 338,270,744,728,154 with Prime Factorization
2 | 338, 270, 744, 728, 154 |
2 | 169, 135, 372, 364, 77 |
2 | 169, 135, 186, 182, 77 |
3 | 169, 135, 93, 91, 77 |
7 | 169, 45, 31, 91, 77 |
13 | 169, 45, 31, 13, 11 |
1, 45, 31, 13, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 13 x 1 x 45 x 31 x 13 x 11 = 435675240
Therefore, the lowest common multiple of 338,270,744,728,154 is 435675240.
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.
338 x 270 x 744 x 728 x 154 = 7612117793280
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.
338 : 1, 2, 13, 26, 169, 338
270 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 90, 135, 270
744 : 1, 2, 3, 4, 6, 8, 12, 24, 31, 62, 93, 124, 186, 248, 372, 744
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
154 : 1, 2, 7, 11, 14, 22, 77, 154
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 338,270,744,728,154, is 2.
Now, the common factors can be found like this.
338:2x 13x 13
270:2x 3x 3x 3x 5
744:2x 2x 2x 3x 31
728:2x 2x 2x 7x 13
154:2x 7x 11
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 2x 2x 3x 7x 13 = 8736
Therefore, the value for common factors is 8736.
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 = 7612117793280/(2x8736)
LCM = 7612117793280/17472
LCM = 435675240
Thus, we can understand that the LCM of 338,270,744,728,154 is 435675240.
