Calculate the LCM of 673,639,837,124

Given numbers are 673,639,837,124

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

The LCM of 673,639,837,124 is 159977484.

Find LCM of 673,639,837,124 with Prime Factorization


3 673, 639, 837, 124
3 673, 213, 279, 124
31 673, 71, 93, 124
673, 71, 3, 4

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

3 x 3 x 31 x 673 x 71 x 3 x 4 = 159977484

Therefore, the lowest common multiple of 673,639,837,124 is 159977484.

LCM Formula to Find Lowest Common Multiple of 673,639,837,124

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.

673 x 639 x 837 x 124 = 44633718036

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.

673 : 1, 673

639 : 1, 3, 9, 71, 213, 639

837 : 1, 3, 9, 27, 31, 93, 279, 837

124 : 1, 2, 4, 31, 62, 124

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 673,639,837,124, is 1.

Now, the common factors can be found like this.

673:673

639:3x 3x 71

837:3x 3x 3x 31

124:2x 2x 31

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 31 = 279

Therefore, the value for common factors is 279.

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 = 44633718036/(1x279)

LCM = 44633718036/279

LCM = 159977484

Thus, we can understand that the LCM of 673,639,837,124 is 159977484.
