Given numbers are 821,524,131,491

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

The LCM of 821,524,131,491 is 211230164.

Find LCM of 821,524,131,491 with Prime Factorization

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

131 x 821 x 4 x 1 x 491 = 211230164

Therefore, the lowest common multiple of 821,524,131,491 is 211230164.

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 524 x 131 x 491 = 27671151484

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

524 : 1, 2, 4, 131, 262, 524

131 : 1, 131

491 : 1, 491

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,524,131,491, is 1.

Now, the common factors can be found like this.

821:821

524:2x 2x 131

131:131

491:491

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

131 = 131

Therefore, the value for common factors is 131.

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 = 27671151484/(1x131)

LCM = 27671151484/131

LCM = 211230164

Thus, we can understand that the LCM of 821,524,131,491 is 211230164.
