Given numbers are 124,238,289,857

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

The LCM of 124,238,289,857 is 214980164.

Find LCM of 124,238,289,857 with Prime Factorization

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

2 x 17 x 62 x 7 x 17 x 857 = 214980164

Therefore, the lowest common multiple of 124,238,289,857 is 214980164.

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.

124 x 238 x 289 x 857 = 7309325576

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.

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

238 : 1, 2, 7, 14, 17, 34, 119, 238

289 : 1, 17, 289

857 : 1, 857

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 124,238,289,857, is 1.

Now, the common factors can be found like this.

124:2x 2x 31

238:2x 7x 17

289:17x 17

857:857

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 17 = 34

Therefore, the value for common factors is 34.

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 = 7309325576/(1x34)

LCM = 7309325576/34

LCM = 214980164

Thus, we can understand that the LCM of 124,238,289,857 is 214980164.
