Calculate the LCM of 642,211,211,235,244

Given numbers are 642,211,211,235,244

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

The LCM of 642,211,211,235,244 is 3883695540.

Find LCM of 642,211,211,235,244 with Prime Factorization


2 642, 211, 211, 235, 244
211 321, 211, 211, 235, 122
321, 1, 1, 235, 122

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

2 x 211 x 321 x 1 x 1 x 235 x 122 = 3883695540

Therefore, the lowest common multiple of 642,211,211,235,244 is 3883695540.

LCM Formula to Find Lowest Common Multiple of 642,211,211,235,244

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.

642 x 211 x 211 x 235 x 244 = 1638919517880

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.

642 : 1, 2, 3, 6, 107, 214, 321, 642

211 : 1, 211

211 : 1, 211

235 : 1, 5, 47, 235

244 : 1, 2, 4, 61, 122, 244

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,211,211,235,244, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

211:211

211:211

235:5x 47

244:2x 2x 61

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

2x 211 = 422

Therefore, the value for common factors is 422.

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 = 1638919517880/(1x422)

LCM = 1638919517880/422

LCM = 3883695540

Thus, we can understand that the LCM of 642,211,211,235,244 is 3883695540.
