Given numbers are 128,438,212,543

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 128,438,212,543 is 268910976.

Find LCM of 128,438,212,543 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 2 x 3 x 32 x 73 x 53 x 181 = 268910976

Therefore, the lowest common multiple of 128,438,212,543 is 268910976.

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.

128 x 438 x 212 x 543 = 6453863424

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.

128 : 1, 2, 4, 8, 16, 32, 64, 128

438 : 1, 2, 3, 6, 73, 146, 219, 438

212 : 1, 2, 4, 53, 106, 212

543 : 1, 3, 181, 543

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,438,212,543, is 1.

Now, the common factors can be found like this.

128:2x 2x 2x 2x 2x 2x 2

438:2x 3x 73

212:2x 2x 53

543:3x 181

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 3 = 24

Therefore, the value for common factors is 24.

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 = 6453863424/(1x24)

LCM = 6453863424/24

LCM = 268910976

Thus, we can understand that the LCM of 128,438,212,543 is 268910976.
