Given numbers are 845,395,215,972

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

The LCM of 845,395,215,972 is 2790091980.

Find LCM of 845,395,215,972 with Prime Factorization

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

5 x 169 x 79 x 43 x 972 = 2790091980

Therefore, the lowest common multiple of 845,395,215,972 is 2790091980.

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.

845 x 395 x 215 x 972 = 69752299500

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.

845 : 1, 5, 13, 65, 169, 845

395 : 1, 5, 79, 395

215 : 1, 5, 43, 215

972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 845,395,215,972, is 1.

Now, the common factors can be found like this.

845:5x 13x 13

395:5x 79

215:5x 43

972:2x 2x 3x 3x 3x 3x 3

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

5x 5 = 25

Therefore, the value for common factors is 25.

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 = 69752299500/(1x25)

LCM = 69752299500/25

LCM = 2790091980

Thus, we can understand that the LCM of 845,395,215,972 is 2790091980.
