Given numbers are 426,455,247,485

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

The LCM of 426,455,247,485 is 357228690.

Find LCM of 426,455,247,485 with Prime Factorization

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

5 x 13 x 426 x 7 x 19 x 97 = 357228690

Therefore, the lowest common multiple of 426,455,247,485 is 357228690.

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.

426 x 455 x 247 x 485 = 23219864850

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.

426 : 1, 2, 3, 6, 71, 142, 213, 426

455 : 1, 5, 7, 13, 35, 65, 91, 455

247 : 1, 13, 19, 247

485 : 1, 5, 97, 485

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 426,455,247,485, is 1.

Now, the common factors can be found like this.

426:2x 3x 71

455:5x 7x 13

247:13x 19

485:5x 97

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

5x 13 = 65

Therefore, the value for common factors is 65.

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 = 23219864850/(1x65)

LCM = 23219864850/65

LCM = 357228690

Thus, we can understand that the LCM of 426,455,247,485 is 357228690.
