Given numbers are 251,346,298,421

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

The LCM of 251,346,298,421 is 5447762734.

Find LCM of 251,346,298,421 with Prime Factorization

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

2 x 251 x 173 x 149 x 421 = 5447762734

Therefore, the lowest common multiple of 251,346,298,421 is 5447762734.

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.

251 x 346 x 298 x 421 = 10895525468

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.

251 : 1, 251

346 : 1, 2, 173, 346

298 : 1, 2, 149, 298

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 251,346,298,421, is 1.

Now, the common factors can be found like this.

251:251

346:2x 173

298:2x 149

421:421

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

2 = 2

Therefore, the value for common factors is 2.

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 = 10895525468/(1x2)

LCM = 10895525468/2

LCM = 5447762734

Thus, we can understand that the LCM of 251,346,298,421 is 5447762734.
