Calculate the LCM of 838,891,161,292,139

Given numbers are 838,891,161,292,139

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

The LCM of 838,891,161,292,139 is 2439581069772.

Find LCM of 838,891,161,292,139 with Prime Factorization


2 838, 891, 161, 292, 139
419, 891, 161, 146, 139

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

2 x 419 x 891 x 161 x 146 x 139 = 2439581069772

Therefore, the lowest common multiple of 838,891,161,292,139 is 2439581069772.

LCM Formula to Find Lowest Common Multiple of 838,891,161,292,139

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.

838 x 891 x 161 x 292 x 139 = 4879162139544

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.

838 : 1, 2, 419, 838

891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891

161 : 1, 7, 23, 161

292 : 1, 2, 4, 73, 146, 292

139 : 1, 139

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 838,891,161,292,139, is 1.

Now, the common factors can be found like this.

838:2x 419

891:3x 3x 3x 3x 11

161:7x 23

292:2x 2x 73

139:139

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

2 = 2

Therefore, the value for common factors is 2.

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 = 4879162139544/(1x2)

LCM = 4879162139544/2

LCM = 2439581069772

Thus, we can understand that the LCM of 838,891,161,292,139 is 2439581069772.
