Given numbers are 155,128,279,283

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

The LCM of 155,128,279,283 is 50532480.

Find LCM of 155,128,279,283 with Prime Factorization

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

31 x 5 x 128 x 9 x 283 = 50532480

Therefore, the lowest common multiple of 155,128,279,283 is 50532480.

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.

155 x 128 x 279 x 283 = 1566506880

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.

155 : 1, 5, 31, 155

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

279 : 1, 3, 9, 31, 93, 279

283 : 1, 283

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 155,128,279,283, is 1.

Now, the common factors can be found like this.

155:5x 31

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

279:3x 3x 31

283:283

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

31 = 31

Therefore, the value for common factors is 31.

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 = 1566506880/(1x31)

LCM = 1566506880/31

LCM = 50532480

Thus, we can understand that the LCM of 155,128,279,283 is 50532480.
