Given numbers are 253,521,781,451

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

The LCM of 253,521,781,451 is 383707643.

Find LCM of 253,521,781,451 with Prime Factorization

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

11 x 23 x 521 x 71 x 41 = 383707643

Therefore, the lowest common multiple of 253,521,781,451 is 383707643.

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.

253 x 521 x 781 x 451 = 46428624803

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.

253 : 1, 11, 23, 253

521 : 1, 521

781 : 1, 11, 71, 781

451 : 1, 11, 41, 451

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 253,521,781,451, is 1.

Now, the common factors can be found like this.

253:11x 23

521:521

781:11x 71

451:11x 41

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

11x 11 = 121

Therefore, the value for common factors is 121.

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 = 46428624803/(1x121)

LCM = 46428624803/121

LCM = 383707643

Thus, we can understand that the LCM of 253,521,781,451 is 383707643.
