Given numbers are 494,487,245,57

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

The LCM of 494,487,245,57 is 176824830.

Find LCM of 494,487,245,57 with Prime Factorization

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

19 x 26 x 487 x 245 x 3 = 176824830

Therefore, the lowest common multiple of 494,487,245,57 is 176824830.

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.

494 x 487 x 245 x 57 = 3359671770

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.

494 : 1, 2, 13, 19, 26, 38, 247, 494

487 : 1, 487

245 : 1, 5, 7, 35, 49, 245

57 : 1, 3, 19, 57

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 494,487,245,57, is 1.

Now, the common factors can be found like this.

494:2x 13x 19

487:487

245:5x 7x 7

57:3x 19

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

19 = 19

Therefore, the value for common factors is 19.

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 = 3359671770/(1x19)

LCM = 3359671770/19

LCM = 176824830

Thus, we can understand that the LCM of 494,487,245,57 is 176824830.
