Given numbers are 556,531,989,681,256
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 556,531,989,681,256 is 4242007533312.
Find LCM of 556,531,989,681,256 with Prime Factorization
| 2 | 556, 531, 989, 681, 256 |
| 2 | 278, 531, 989, 681, 128 |
| 3 | 139, 531, 989, 681, 64 |
| 139, 177, 989, 227, 64 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 139 x 177 x 989 x 227 x 64 = 4242007533312
Therefore, the lowest common multiple of 556,531,989,681,256 is 4242007533312.
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.
556 x 531 x 989 x 681 x 256 = 50904090399744
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.
556 : 1, 2, 4, 139, 278, 556
531 : 1, 3, 9, 59, 177, 531
989 : 1, 23, 43, 989
681 : 1, 3, 227, 681
256 : 1, 2, 4, 8, 16, 32, 64, 128, 256
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 556,531,989,681,256, is 1.
Now, the common factors can be found like this.
556:2x 2x 139
531:3x 3x 59
989:23x 43
681:3x 227
256:2x 2x 2x 2x 2x 2x 2x 2
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 3 = 12
Therefore, the value for common factors is 12.
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 = 50904090399744/(1x12)
LCM = 50904090399744/12
LCM = 4242007533312
Thus, we can understand that the LCM of 556,531,989,681,256 is 4242007533312.
