Given numbers are 821,254,291,508

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

The LCM of 821,254,291,508 is 121366788.

Find LCM of 821,254,291,508 with Prime Factorization

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

2 x 127 x 821 x 1 x 291 x 2 = 121366788

Therefore, the lowest common multiple of 821,254,291,508 is 121366788.

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.

821 x 254 x 291 x 508 = 30827164152

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.

821 : 1, 821

254 : 1, 2, 127, 254

291 : 1, 3, 97, 291

508 : 1, 2, 4, 127, 254, 508

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,254,291,508, is 1.

Now, the common factors can be found like this.

821:821

254:2x 127

291:3x 97

508:2x 2x 127

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

2x 127 = 254

Therefore, the value for common factors is 254.

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 = 30827164152/(1x254)

LCM = 30827164152/254

LCM = 121366788

Thus, we can understand that the LCM of 821,254,291,508 is 121366788.
