Given numbers are 821,602,445,386

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

The LCM of 821,602,445,386 is 42447974170.

Find LCM of 821,602,445,386 with Prime Factorization

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

2 x 821 x 301 x 445 x 193 = 42447974170

Therefore, the lowest common multiple of 821,602,445,386 is 42447974170.

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 602 x 445 x 386 = 84895948340

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

602 : 1, 2, 7, 14, 43, 86, 301, 602

445 : 1, 5, 89, 445

386 : 1, 2, 193, 386

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,602,445,386, is 1.

Now, the common factors can be found like this.

821:821

602:2x 7x 43

445:5x 89

386:2x 193

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

2 = 2

Therefore, the value for common factors is 2.

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 = 84895948340/(1x2)

LCM = 84895948340/2

LCM = 42447974170

Thus, we can understand that the LCM of 821,602,445,386 is 42447974170.
