Calculate the LCM of 838,856,689,419

Given numbers are 838,856,689,419

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

The LCM of 838,856,689,419 is 247119496.

Find LCM of 838,856,689,419 with Prime Factorization


2 838, 856, 689, 419
419 419, 428, 689, 419
1, 428, 689, 1

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

2 x 419 x 1 x 428 x 689 x 1 = 247119496

Therefore, the lowest common multiple of 838,856,689,419 is 247119496.

LCM Formula to Find Lowest Common Multiple of 838,856,689,419

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 856 x 689 x 419 = 207086137648

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

856 : 1, 2, 4, 8, 107, 214, 428, 856

689 : 1, 13, 53, 689

419 : 1, 419

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 838,856,689,419, is 1.

Now, the common factors can be found like this.

838:2x 419

856:2x 2x 2x 107

689:13x 53

419:419

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

2x 419 = 838

Therefore, the value for common factors is 838.

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 = 207086137648/(1x838)

LCM = 207086137648/838

LCM = 247119496

Thus, we can understand that the LCM of 838,856,689,419 is 247119496.
