Calculate the LCM of 643,171,279,119

Given numbers are 643,171,279,119

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

The LCM of 643,171,279,119 is 405616617.

Find LCM of 643,171,279,119 with Prime Factorization


3 643, 171, 279, 119
3 643, 57, 93, 119
643, 19, 31, 119

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

3 x 3 x 643 x 19 x 31 x 119 = 405616617

Therefore, the lowest common multiple of 643,171,279,119 is 405616617.

LCM Formula to Find Lowest Common Multiple of 643,171,279,119

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.

643 x 171 x 279 x 119 = 3650549553

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.

643 : 1, 643

171 : 1, 3, 9, 19, 57, 171

279 : 1, 3, 9, 31, 93, 279

119 : 1, 7, 17, 119

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,171,279,119, is 1.

Now, the common factors can be found like this.

643:643

171:3x 3x 19

279:3x 3x 31

119:7x 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 3 = 9

Therefore, the value for common factors is 9.

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 = 3650549553/(1x9)

LCM = 3650549553/9

LCM = 405616617

Thus, we can understand that the LCM of 643,171,279,119 is 405616617.
