Given numbers are 298,145,406,251

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

The LCM of 298,145,406,251 is 75919970.

Find LCM of 298,145,406,251 with Prime Factorization

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

2 x 29 x 149 x 5 x 7 x 251 = 75919970

Therefore, the lowest common multiple of 298,145,406,251 is 75919970.

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.

298 x 145 x 406 x 251 = 4403358260

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.

298 : 1, 2, 149, 298

145 : 1, 5, 29, 145

406 : 1, 2, 7, 14, 29, 58, 203, 406

251 : 1, 251

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 298,145,406,251, is 1.

Now, the common factors can be found like this.

298:2x 149

145:5x 29

406:2x 7x 29

251:251

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

2x 29 = 58

Therefore, the value for common factors is 58.

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 = 4403358260/(1x58)

LCM = 4403358260/58

LCM = 75919970

Thus, we can understand that the LCM of 298,145,406,251 is 75919970.
