Calculate the LCM of 669,357,231,340

Given numbers are 669,357,231,340

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

The LCM of 669,357,231,340 is 17514420.

Find LCM of 669,357,231,340 with Prime Factorization


3 669, 357, 231, 340
7 223, 119, 77, 340
17 223, 17, 11, 340
223, 1, 11, 20

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

3 x 7 x 17 x 223 x 1 x 11 x 20 = 17514420

Therefore, the lowest common multiple of 669,357,231,340 is 17514420.

LCM Formula to Find Lowest Common Multiple of 669,357,231,340

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.

669 x 357 x 231 x 340 = 18757943820

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.

669 : 1, 3, 223, 669

357 : 1, 3, 7, 17, 21, 51, 119, 357

231 : 1, 3, 7, 11, 21, 33, 77, 231

340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 669,357,231,340, is 1.

Now, the common factors can be found like this.

669:3x 223

357:3x 7x 17

231:3x 7x 11

340:2x 2x 5x 17

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

3x 3x 7x 17 = 1071

Therefore, the value for common factors is 1071.

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 = 18757943820/(1x1071)

LCM = 18757943820/1071

LCM = 17514420

Thus, we can understand that the LCM of 669,357,231,340 is 17514420.
