Given numbers are 213,124,128,639

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

The LCM of 213,124,128,639 is 2535552.

Find LCM of 213,124,128,639 with Prime Factorization

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

2 x 2 x 3 x 71 x 1 x 31 x 32 x 3 = 2535552

Therefore, the lowest common multiple of 213,124,128,639 is 2535552.

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.

213 x 124 x 128 x 639 = 2160290304

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.

213 : 1, 3, 71, 213

124 : 1, 2, 4, 31, 62, 124

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

639 : 1, 3, 9, 71, 213, 639

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 213,124,128,639, is 1.

Now, the common factors can be found like this.

213:3x 71

124:2x 2x 31

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

639:3x 3x 71

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 3x 71 = 852

Therefore, the value for common factors is 852.

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 = 2160290304/(1x852)

LCM = 2160290304/852

LCM = 2535552

Thus, we can understand that the LCM of 213,124,128,639 is 2535552.
