Calculate the LCM of 768,117,221,253

Given numbers are 768,117,221,253

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

The LCM of 768,117,221,253 is 128823552.

Find LCM of 768,117,221,253 with Prime Factorization


3 768, 117, 221, 253
13 256, 39, 221, 253
256, 3, 17, 253

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

3 x 13 x 256 x 3 x 17 x 253 = 128823552

Therefore, the lowest common multiple of 768,117,221,253 is 128823552.

LCM Formula to Find Lowest Common Multiple of 768,117,221,253

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.

768 x 117 x 221 x 253 = 5024118528

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.

768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768

117 : 1, 3, 9, 13, 39, 117

221 : 1, 13, 17, 221

253 : 1, 11, 23, 253

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 768,117,221,253, is 1.

Now, the common factors can be found like this.

768:2x 2x 2x 2x 2x 2x 2x 2x 3

117:3x 3x 13

221:13x 17

253:11x 23

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

3x 13 = 39

Therefore, the value for common factors is 39.

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 = 5024118528/(1x39)

LCM = 5024118528/39

LCM = 128823552

Thus, we can understand that the LCM of 768,117,221,253 is 128823552.
