Find LCM of 247,416,645,704 with Prime Factorization
2 | 247, 416, 645, 704 |
2 | 247, 208, 645, 352 |
2 | 247, 104, 645, 176 |
2 | 247, 52, 645, 88 |
2 | 247, 26, 645, 44 |
13 | 247, 13, 645, 22 |
19, 1, 645, 22 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 13 x 19 x 1 x 645 x 22 = 112157760
Therefore, the lowest common multiple of 247,416,645,704 is 112157760.
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.
247 x 416 x 645 x 704 = 46657628160
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.
247 : 1, 13, 19, 247
416 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 104, 208, 416
645 : 1, 3, 5, 15, 43, 129, 215, 645
704 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 64, 88, 176, 352, 704
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 247,416,645,704, is 1.
Now, the common factors can be found like this.
247:13x 19
416:2x 2x 2x 2x 2x 13
645:3x 5x 43
704:2x 2x 2x 2x 2x 2x 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 13 = 416
Therefore, the value for common factors is 416.
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 = 46657628160/(1x416)
LCM = 46657628160/416
LCM = 112157760
Thus, we can understand that the LCM of 247,416,645,704 is 112157760.
