Given numbers are 854,307,161,721

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

The LCM of 854,307,161,721 is 621099682.

Find LCM of 854,307,161,721 with Prime Factorization

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

7 x 122 x 307 x 23 x 103 = 621099682

Therefore, the lowest common multiple of 854,307,161,721 is 621099682.

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.

854 x 307 x 161 x 721 = 30433884418

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.

854 : 1, 2, 7, 14, 61, 122, 427, 854

307 : 1, 307

161 : 1, 7, 23, 161

721 : 1, 7, 103, 721

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 854,307,161,721, is 1.

Now, the common factors can be found like this.

854:2x 7x 61

307:307

161:7x 23

721:7x 103

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

7x 7 = 49

Therefore, the value for common factors is 49.

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 = 30433884418/(1x49)

LCM = 30433884418/49

LCM = 621099682

Thus, we can understand that the LCM of 854,307,161,721 is 621099682.
