Given numbers are 257,492,707,505

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

The LCM of 257,492,707,505 is 446979540.

Find LCM of 257,492,707,505 with Prime Factorization

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

101 x 257 x 492 x 7 x 5 = 446979540

Therefore, the lowest common multiple of 257,492,707,505 is 446979540.

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.

257 x 492 x 707 x 505 = 45144933540

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.

257 : 1, 257

492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492

707 : 1, 7, 101, 707

505 : 1, 5, 101, 505

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 257,492,707,505, is 1.

Now, the common factors can be found like this.

257:257

492:2x 2x 3x 41

707:7x 101

505:5x 101

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

101 = 101

Therefore, the value for common factors is 101.

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 = 45144933540/(1x101)

LCM = 45144933540/101

LCM = 446979540

Thus, we can understand that the LCM of 257,492,707,505 is 446979540.
