Find LCM of 681,856,704,550 with Prime Factorization
2 | 681, 856, 704, 550 |
2 | 681, 428, 352, 275 |
2 | 681, 214, 176, 275 |
11 | 681, 107, 88, 275 |
681, 107, 8, 25 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 11 x 681 x 107 x 8 x 25 = 1282459200
Therefore, the lowest common multiple of 681,856,704,550 is 1282459200.
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.
681 x 856 x 704 x 550 = 225712819200
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.
681 : 1, 3, 227, 681
856 : 1, 2, 4, 8, 107, 214, 428, 856
704 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 64, 88, 176, 352, 704
550 : 1, 2, 5, 10, 11, 22, 25, 50, 55, 110, 275, 550
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 681,856,704,550, is 1.
Now, the common factors can be found like this.
681:3x 227
856:2x 2x 2x 107
704:2x 2x 2x 2x 2x 2x 11
550:2x 5x 5x 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 11 = 176
Therefore, the value for common factors is 176.
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 = 225712819200/(1x176)
LCM = 225712819200/176
LCM = 1282459200
Thus, we can understand that the LCM of 681,856,704,550 is 1282459200.
