Given numbers are 420,281,782,326

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

The LCM of 420,281,782,326 is 7521768660.

Find LCM of 420,281,782,326 with Prime Factorization

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

2 x 210 x 281 x 391 x 163 = 7521768660

Therefore, the lowest common multiple of 420,281,782,326 is 7521768660.

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.

420 x 281 x 782 x 326 = 30087074640

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.

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

281 : 1, 281

782 : 1, 2, 17, 23, 34, 46, 391, 782

326 : 1, 2, 163, 326

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 420,281,782,326, is 1.

Now, the common factors can be found like this.

420:2x 2x 3x 5x 7

281:281

782:2x 17x 23

326:2x 163

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 = 30087074640/(1x4)

LCM = 30087074640/4

LCM = 7521768660

Thus, we can understand that the LCM of 420,281,782,326 is 7521768660.
