Find LCM of 428,800,297,756,434 with Prime Factorization
2 | 428, 800, 297, 756, 434 |
2 | 214, 400, 297, 378, 217 |
3 | 107, 200, 297, 189, 217 |
3 | 107, 200, 99, 63, 217 |
3 | 107, 200, 33, 21, 217 |
7 | 107, 200, 11, 7, 217 |
107, 200, 11, 1, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 3 x 7 x 107 x 200 x 11 x 1 x 31 = 5516834400
Therefore, the lowest common multiple of 428,800,297,756,434 is 5516834400.
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.
428 x 800 x 297 x 756 x 434 = 33365814451200
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.
428 : 1, 2, 4, 107, 214, 428
800 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, 800
297 : 1, 3, 9, 11, 27, 33, 99, 297
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
434 : 1, 2, 7, 14, 31, 62, 217, 434
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 428,800,297,756,434, is 1.
Now, the common factors can be found like this.
428:2x 2x 107
800:2x 2x 2x 2x 2x 5x 5
297:3x 3x 3x 11
756:2x 2x 3x 3x 3x 7
434:2x 7x 31
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 3x 3x 7 = 6048
Therefore, the value for common factors is 6048.
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 = 33365814451200/(1x6048)
LCM = 33365814451200/6048
LCM = 5516834400
Thus, we can understand that the LCM of 428,800,297,756,434 is 5516834400.
