Given numbers are 769,884,871,221

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

The LCM of 769,884,871,221 is 45546332.

Find LCM of 769,884,871,221 with Prime Factorization

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

13 x 17 x 769 x 4 x 67 x 1 = 45546332

Therefore, the lowest common multiple of 769,884,871,221 is 45546332.

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.

769 x 884 x 871 x 221 = 130854611836

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.

769 : 1, 769

884 : 1, 2, 4, 13, 17, 26, 34, 52, 68, 221, 442, 884

871 : 1, 13, 67, 871

221 : 1, 13, 17, 221

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 769,884,871,221, is 1.

Now, the common factors can be found like this.

769:769

884:2x 2x 13x 17

871:13x 67

221:13x 17

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

13x 13x 17 = 2873

Therefore, the value for common factors is 2873.

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 = 130854611836/(1x2873)

LCM = 130854611836/2873

LCM = 45546332

Thus, we can understand that the LCM of 769,884,871,221 is 45546332.
