Given numbers are 815,357,163,971

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

The LCM of 815,357,163,971 is 282517305.

Find LCM of 815,357,163,971 with Prime Factorization

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

163 x 5 x 357 x 1 x 971 = 282517305

Therefore, the lowest common multiple of 815,357,163,971 is 282517305.

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.

815 x 357 x 163 x 971 = 46050320715

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.

815 : 1, 5, 163, 815

357 : 1, 3, 7, 17, 21, 51, 119, 357

163 : 1, 163

971 : 1, 971

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 815,357,163,971, is 1.

Now, the common factors can be found like this.

815:5x 163

357:3x 7x 17

163:163

971:971

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

163 = 163

Therefore, the value for common factors is 163.

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 = 46050320715/(1x163)

LCM = 46050320715/163

LCM = 282517305

Thus, we can understand that the LCM of 815,357,163,971 is 282517305.
