Given numbers are 428,538,733

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

The LCM of 428,538,733 is 84391756.

Find LCM of 428,538,733 with Prime Factorization

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

2 x 214 x 269 x 733 = 84391756

Therefore, the lowest common multiple of 428,538,733 is 84391756.

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 538 x 733 = 168783512

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

538 : 1, 2, 269, 538

733 : 1, 733

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 428,538,733, is 1.

Now, the common factors can be found like this.

428:2x 2x 107

538:2x 269

733:733

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

2 = 2

Therefore, the value for common factors is 2.

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 = 168783512/(1x2)

LCM = 168783512/2

LCM = 84391756

Thus, we can understand that the LCM of 428,538,733 is 84391756.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 289, 439, 189
• LCM of 654, 824, 393
