Given numbers are 642,556,247,274,266

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

The LCM of 642,556,247,274,266 is 42276145548.

Find LCM of 642,556,247,274,266 with Prime Factorization

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

2 x 19 x 321 x 278 x 13 x 137 x 7 = 42276145548

Therefore, the lowest common multiple of 642,556,247,274,266 is 42276145548.

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.

642 x 556 x 247 x 274 x 266 = 6425974123296

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.

642 : 1, 2, 3, 6, 107, 214, 321, 642

556 : 1, 2, 4, 139, 278, 556

247 : 1, 13, 19, 247

274 : 1, 2, 137, 274

266 : 1, 2, 7, 14, 19, 38, 133, 266

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,556,247,274,266, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

556:2x 2x 139

247:13x 19

274:2x 137

266:2x 7x 19

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 19 = 152

Therefore, the value for common factors is 152.

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 = 6425974123296/(1x152)

LCM = 6425974123296/152

LCM = 42276145548

Thus, we can understand that the LCM of 642,556,247,274,266 is 42276145548.
