Given numbers are 821,695,406,610

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

The LCM of 821,695,406,610 is 14131355770.

Find LCM of 821,695,406,610 with Prime Factorization

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

2 x 5 x 821 x 139 x 203 x 61 = 14131355770

Therefore, the lowest common multiple of 821,695,406,610 is 14131355770.

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 695 x 406 x 610 = 141313557700

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

695 : 1, 5, 139, 695

406 : 1, 2, 7, 14, 29, 58, 203, 406

610 : 1, 2, 5, 10, 61, 122, 305, 610

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,695,406,610, is 1.

Now, the common factors can be found like this.

821:821

695:5x 139

406:2x 7x 29

610:2x 5x 61

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 141313557700/(1x10)

LCM = 141313557700/10

LCM = 14131355770

Thus, we can understand that the LCM of 821,695,406,610 is 14131355770.
