Given numbers are 671,775,403,39

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

The LCM of 671,775,403,39 is 20280975.

Find LCM of 671,775,403,39 with Prime Factorization

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

13 x 31 x 671 x 25 x 1 x 3 = 20280975

Therefore, the lowest common multiple of 671,775,403,39 is 20280975.

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.

671 x 775 x 403 x 39 = 8173232925

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.

671 : 1, 11, 61, 671

775 : 1, 5, 25, 31, 155, 775

403 : 1, 13, 31, 403

39 : 1, 3, 13, 39

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 671,775,403,39, is 1.

Now, the common factors can be found like this.

671:11x 61

775:5x 5x 31

403:13x 31

39:3x 13

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

13x 31 = 403

Therefore, the value for common factors is 403.

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 = 8173232925/(1x403)

LCM = 8173232925/403

LCM = 20280975

Thus, we can understand that the LCM of 671,775,403,39 is 20280975.
