Given numbers are 693,720,871,891

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

The LCM of 693,720,871,891 is 434594160.

Find LCM of 693,720,871,891 with Prime Factorization

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

3 x 3 x 11 x 7 x 80 x 871 x 9 = 434594160

Therefore, the lowest common multiple of 693,720,871,891 is 434594160.

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.

693 x 720 x 871 x 891 = 387223396560

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.

693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693

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

871 : 1, 13, 67, 871

891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 693,720,871,891, is 1.

Now, the common factors can be found like this.

693:3x 3x 7x 11

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

871:13x 67

891:3x 3x 3x 3x 11

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

3x 3x 3x 3x 11 = 891

Therefore, the value for common factors is 891.

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 = 387223396560/(1x891)

LCM = 387223396560/891

LCM = 434594160

Thus, we can understand that the LCM of 693,720,871,891 is 434594160.
