Given numbers are 671,517,661,743

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

The LCM of 671,517,661,743 is 15488546051.

Find LCM of 671,517,661,743 with Prime Factorization

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

11 x 61 x 47 x 661 x 743 = 15488546051

Therefore, the lowest common multiple of 671,517,661,743 is 15488546051.

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 517 x 661 x 743 = 170374006561

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

517 : 1, 11, 47, 517

661 : 1, 661

743 : 1, 743

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 671,517,661,743, is 1.

Now, the common factors can be found like this.

671:11x 61

517:11x 47

661:661

743:743

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

11 = 11

Therefore, the value for common factors is 11.

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 = 170374006561/(1x11)

LCM = 170374006561/11

LCM = 15488546051

Thus, we can understand that the LCM of 671,517,661,743 is 15488546051.
