Given numbers are 428,769,729,769

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

The LCM of 428,769,729,769 is 239937228.

Find LCM of 428,769,729,769 with Prime Factorization

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

769 x 428 x 1 x 729 x 1 = 239937228

Therefore, the lowest common multiple of 428,769,729,769 is 239937228.

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.

428 x 769 x 729 x 769 = 184511728332

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.

428 : 1, 2, 4, 107, 214, 428

769 : 1, 769

729 : 1, 3, 9, 27, 81, 243, 729

769 : 1, 769

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 428,769,729,769, is 1.

Now, the common factors can be found like this.

428:2x 2x 107

769:769

729:3x 3x 3x 3x 3x 3

769:769

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

769 = 769

Therefore, the value for common factors is 769.

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 = 184511728332/(1x769)

LCM = 184511728332/769

LCM = 239937228

Thus, we can understand that the LCM of 428,769,729,769 is 239937228.
