Given numbers are 781,319,571,253

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

The LCM of 781,319,571,253 is 297449317.

Find LCM of 781,319,571,253 with Prime Factorization

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

11 x 71 x 29 x 571 x 23 = 297449317

Therefore, the lowest common multiple of 781,319,571,253 is 297449317.

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.

781 x 319 x 571 x 253 = 35991367357

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.

781 : 1, 11, 71, 781

319 : 1, 11, 29, 319

571 : 1, 571

253 : 1, 11, 23, 253

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,319,571,253, is 1.

Now, the common factors can be found like this.

781:11x 71

319:11x 29

571:571

253:11x 23

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 = 35991367357/(1x121)

LCM = 35991367357/121

LCM = 297449317

Thus, we can understand that the LCM of 781,319,571,253 is 297449317.
