Given numbers are 821,403,905,533

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

The LCM of 821,403,905,533 is 12276671615.

Find LCM of 821,403,905,533 with Prime Factorization

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

13 x 821 x 31 x 905 x 41 = 12276671615

Therefore, the lowest common multiple of 821,403,905,533 is 12276671615.

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 403 x 905 x 533 = 159596730995

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

403 : 1, 13, 31, 403

905 : 1, 5, 181, 905

533 : 1, 13, 41, 533

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,403,905,533, is 1.

Now, the common factors can be found like this.

821:821

403:13x 31

905:5x 181

533:13x 41

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

13 = 13

Therefore, the value for common factors is 13.

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 = 159596730995/(1x13)

LCM = 159596730995/13

LCM = 12276671615

Thus, we can understand that the LCM of 821,403,905,533 is 12276671615.
