Given numbers are 856,506,421,489

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

The LCM of 856,506,421,489 is 44584637592.

Find LCM of 856,506,421,489 with Prime Factorization

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

2 x 428 x 253 x 421 x 489 = 44584637592

Therefore, the lowest common multiple of 856,506,421,489 is 44584637592.

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.

856 x 506 x 421 x 489 = 89169275184

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.

856 : 1, 2, 4, 8, 107, 214, 428, 856

506 : 1, 2, 11, 22, 23, 46, 253, 506

421 : 1, 421

489 : 1, 3, 163, 489

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 856,506,421,489, is 1.

Now, the common factors can be found like this.

856:2x 2x 2x 107

506:2x 11x 23

421:421

489:3x 163

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 = 89169275184/(1x2)

LCM = 89169275184/2

LCM = 44584637592

Thus, we can understand that the LCM of 856,506,421,489 is 44584637592.
