Calculate the LCM of 428,286,118,286

Given numbers are 428,286,118,286

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

The LCM of 428,286,118,286 is 3611036.

Find LCM of 428,286,118,286 with Prime Factorization


2 428, 286, 118, 286
11 214, 143, 59, 143
13 214, 13, 59, 13
214, 1, 59, 1

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

2 x 11 x 13 x 214 x 1 x 59 x 1 = 3611036

Therefore, the lowest common multiple of 428,286,118,286 is 3611036.

LCM Formula to Find Lowest Common Multiple of 428,286,118,286

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 286 x 118 x 286 = 4131025184

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

286 : 1, 2, 11, 13, 22, 26, 143, 286

118 : 1, 2, 59, 118

286 : 1, 2, 11, 13, 22, 26, 143, 286

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 428,286,118,286, is 2.

Now, the common factors can be found like this.

428:2x 2x 107

286:2x 11x 13

118:2x 59

286:2x 11x 13

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

2x 2x 11x 13 = 572

Therefore, the value for common factors is 572.

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 = 4131025184/(2x572)

LCM = 4131025184/1144

LCM = 3611036

Thus, we can understand that the LCM of 428,286,118,286 is 3611036.
