Given numbers are 820,769,586,438

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

The LCM of 820,769,586,438 is 40462426860.

Find LCM of 820,769,586,438 with Prime Factorization

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

2 x 410 x 769 x 293 x 219 = 40462426860

Therefore, the lowest common multiple of 820,769,586,438 is 40462426860.

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.

820 x 769 x 586 x 438 = 161849707440

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.

820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820

769 : 1, 769

586 : 1, 2, 293, 586

438 : 1, 2, 3, 6, 73, 146, 219, 438

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 820,769,586,438, is 1.

Now, the common factors can be found like this.

820:2x 2x 5x 41

769:769

586:2x 293

438:2x 3x 73

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 161849707440/(1x4)

LCM = 161849707440/4

LCM = 40462426860

Thus, we can understand that the LCM of 820,769,586,438 is 40462426860.
