Given numbers are 248,899,961,645

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

The LCM of 248,899,961,645 is 143804040.

Find LCM of 248,899,961,645 with Prime Factorization

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

31 x 8 x 29 x 31 x 645 = 143804040

Therefore, the lowest common multiple of 248,899,961,645 is 143804040.

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.

248 x 899 x 961 x 645 = 138195682440

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.

248 : 1, 2, 4, 8, 31, 62, 124, 248

899 : 1, 29, 31, 899

961 : 1, 31, 961

645 : 1, 3, 5, 15, 43, 129, 215, 645

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 248,899,961,645, is 1.

Now, the common factors can be found like this.

248:2x 2x 2x 31

899:29x 31

961:31x 31

645:3x 5x 43

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

31x 31 = 961

Therefore, the value for common factors is 961.

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 = 138195682440/(1x961)

LCM = 138195682440/961

LCM = 143804040

Thus, we can understand that the LCM of 248,899,961,645 is 143804040.
