Calculate the LCM of 688,167,209,234,923

Given numbers are 688,167,209,234,923

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

The LCM of 688,167,209,234,923 is 199478184048.

Find LCM of 688,167,209,234,923 with Prime Factorization


2 688, 167, 209, 234, 923
13 344, 167, 209, 117, 923
344, 167, 209, 9, 71

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

2 x 13 x 344 x 167 x 209 x 9 x 71 = 199478184048

Therefore, the lowest common multiple of 688,167,209,234,923 is 199478184048.

LCM Formula to Find Lowest Common Multiple of 688,167,209,234,923

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.

688 x 167 x 209 x 234 x 923 = 5186432785248

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.

688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688

167 : 1, 167

209 : 1, 11, 19, 209

234 : 1, 2, 3, 6, 9, 13, 18, 26, 39, 78, 117, 234

923 : 1, 13, 71, 923

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 688,167,209,234,923, is 1.

Now, the common factors can be found like this.

688:2x 2x 2x 2x 43

167:167

209:11x 19

234:2x 3x 3x 13

923:13x 71

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

2x 13 = 26

Therefore, the value for common factors is 26.

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 = 5186432785248/(1x26)

LCM = 5186432785248/26

LCM = 199478184048

Thus, we can understand that the LCM of 688,167,209,234,923 is 199478184048.
