Calculate the LCM of 447,720,671,707

Given numbers are 447,720,671,707

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

The LCM of 447,720,671,707 is 50893310160.

Find LCM of 447,720,671,707 with Prime Factorization


3 447, 720, 671, 707
149, 240, 671, 707

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

3 x 149 x 240 x 671 x 707 = 50893310160

Therefore, the lowest common multiple of 447,720,671,707 is 50893310160.

LCM Formula to Find Lowest Common Multiple of 447,720,671,707

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.

447 x 720 x 671 x 707 = 152679930480

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.

447 : 1, 3, 149, 447

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

671 : 1, 11, 61, 671

707 : 1, 7, 101, 707

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 447,720,671,707, is 1.

Now, the common factors can be found like this.

447:3x 149

720:2x 2x 2x 2x 3x 3x 5

671:11x 61

707:7x 101

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

3 = 3

Therefore, the value for common factors is 3.

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 = 152679930480/(1x3)

LCM = 152679930480/3

LCM = 50893310160

Thus, we can understand that the LCM of 447,720,671,707 is 50893310160.
