Given numbers are 556,821,424,257
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 556,821,424,257 is 12435319192.
Find LCM of 556,821,424,257 with Prime Factorization
| 2 | 556, 821, 424, 257 |
| 2 | 278, 821, 212, 257 |
| 139, 821, 106, 257 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 139 x 821 x 106 x 257 = 12435319192
Therefore, the lowest common multiple of 556,821,424,257 is 12435319192.
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 821 x 424 x 257 = 49741276768
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
821 : 1, 821
424 : 1, 2, 4, 8, 53, 106, 212, 424
257 : 1, 257
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 556,821,424,257, is 1.
Now, the common factors can be found like this.
556:2x 2x 139
821:821
424:2x 2x 2x 53
257:257
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 49741276768/(1x4)
LCM = 49741276768/4
LCM = 12435319192
Thus, we can understand that the LCM of 556,821,424,257 is 12435319192.
