Given numbers are 821,381,254,887

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

The LCM of 821,381,254,887 is 554908974.

Find LCM of 821,381,254,887 with Prime Factorization

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

127 x 821 x 3 x 2 x 887 = 554908974

Therefore, the lowest common multiple of 821,381,254,887 is 554908974.

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 381 x 254 x 887 = 70473439698

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

381 : 1, 3, 127, 381

254 : 1, 2, 127, 254

887 : 1, 887

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,381,254,887, is 1.

Now, the common factors can be found like this.

821:821

381:3x 127

254:2x 127

887:887

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

127 = 127

Therefore, the value for common factors is 127.

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 = 70473439698/(1x127)

LCM = 70473439698/127

LCM = 554908974

Thus, we can understand that the LCM of 821,381,254,887 is 554908974.
