The LCM of 256,681,589,620,809 is 415356391680.
Find LCM of 256,681,589,620,809 with Prime Factorization
2 | 256, 681, 589, 620, 809 |
2 | 128, 681, 589, 310, 809 |
31 | 64, 681, 589, 155, 809 |
64, 681, 19, 5, 809 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 31 x 64 x 681 x 19 x 5 x 809 = 415356391680
Therefore, the lowest common multiple of 256,681,589,620,809 is 415356391680.
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.
256 x 681 x 589 x 620 x 809 = 51504192568320
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.
256 : 1, 2, 4, 8, 16, 32, 64, 128, 256
681 : 1, 3, 227, 681
589 : 1, 19, 31, 589
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
809 : 1, 809
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 256,681,589,620,809, is 1.
Now, the common factors can be found like this.
256:2x 2x 2x 2x 2x 2x 2x 2
681:3x 227
589:19x 31
620:2x 2x 5x 31
809:809
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 31 = 124
Therefore, the value for common factors is 124.
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 = 51504192568320/(1x124)
LCM = 51504192568320/124
LCM = 415356391680
Thus, we can understand that the LCM of 256,681,589,620,809 is 415356391680.
