Given numbers are 556,216,161,554
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 556,216,161,554 is 1338980328.
Find LCM of 556,216,161,554 with Prime Factorization
2 | 556, 216, 161, 554 |
2 | 278, 108, 161, 277 |
139, 54, 161, 277 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 139 x 54 x 161 x 277 = 1338980328
Therefore, the lowest common multiple of 556,216,161,554 is 1338980328.
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 216 x 161 x 554 = 10711842624
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
216 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 108, 216
161 : 1, 7, 23, 161
554 : 1, 2, 277, 554
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 556,216,161,554, is 1.
Now, the common factors can be found like this.
556:2x 2x 139
216:2x 2x 2x 3x 3x 3
161:7x 23
554:2x 277
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 2 = 8
Therefore, the value for common factors is 8.
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 = 10711842624/(1x8)
LCM = 10711842624/8
LCM = 1338980328
Thus, we can understand that the LCM of 556,216,161,554 is 1338980328.
