Calculate the LCM of 931,231,427,209

Given numbers are 931,231,427,209

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

The LCM of 931,231,427,209 is 1874103.

Find LCM of 931,231,427,209 with Prime Factorization


7 931, 231, 427, 209
11 133, 33, 61, 209
19 133, 3, 61, 19
7, 3, 61, 1

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

7 x 11 x 19 x 7 x 3 x 61 x 1 = 1874103

Therefore, the lowest common multiple of 931,231,427,209 is 1874103.

LCM Formula to Find Lowest Common Multiple of 931,231,427,209

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.

931 x 231 x 427 x 209 = 19192688823

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.

931 : 1, 7, 19, 49, 133, 931

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

427 : 1, 7, 61, 427

209 : 1, 11, 19, 209

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 931,231,427,209, is 1.

Now, the common factors can be found like this.

931:7x 7x 19

231:3x 7x 11

427:7x 61

209:11x 19

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

7x 7x 11x 19 = 10241

Therefore, the value for common factors is 10241.

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 = 19192688823/(1x10241)

LCM = 19192688823/10241

LCM = 1874103

Thus, we can understand that the LCM of 931,231,427,209 is 1874103.
