Calculate the LCM of 821,728,429,569

Given numbers are 821,728,429,569

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

The LCM of 821,728,429,569 is 11222787576.

Find LCM of 821,728,429,569 with Prime Factorization


13 821, 728, 429, 569
821, 56, 33, 569

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

13 x 821 x 56 x 33 x 569 = 11222787576

Therefore, the lowest common multiple of 821,728,429,569 is 11222787576.

LCM Formula to Find Lowest Common Multiple of 821,728,429,569

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 728 x 429 x 569 = 145896238488

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

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

429 : 1, 3, 11, 13, 33, 39, 143, 429

569 : 1, 569

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,728,429,569, is 1.

Now, the common factors can be found like this.

821:821

728:2x 2x 2x 7x 13

429:3x 11x 13

569:569

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 = 145896238488/(1x13)

LCM = 145896238488/13

LCM = 11222787576

Thus, we can understand that the LCM of 821,728,429,569 is 11222787576.
