Given numbers are 254,507,145,28

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

The LCM of 254,507,145,28 is 261419340.

Find LCM of 254,507,145,28 with Prime Factorization

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

2 x 127 x 507 x 145 x 14 = 261419340

Therefore, the lowest common multiple of 254,507,145,28 is 261419340.

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.

254 x 507 x 145 x 28 = 522838680

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.

254 : 1, 2, 127, 254

507 : 1, 3, 13, 39, 169, 507

145 : 1, 5, 29, 145

28 : 1, 2, 4, 7, 14, 28

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 254,507,145,28, is 1.

Now, the common factors can be found like this.

254:2x 127

507:3x 13x 13

145:5x 29

28:2x 2x 7

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 = 522838680/(1x2)

LCM = 522838680/2

LCM = 261419340

Thus, we can understand that the LCM of 254,507,145,28 is 261419340.
