Given numbers are 838,515,721,244

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

The LCM of 838,515,721,244 is 368560780.

Find LCM of 838,515,721,244 with Prime Factorization

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

2 x 103 x 419 x 5 x 7 x 122 = 368560780

Therefore, the lowest common multiple of 838,515,721,244 is 368560780.

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 515 x 721 x 244 = 75923520680

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

515 : 1, 5, 103, 515

721 : 1, 7, 103, 721

244 : 1, 2, 4, 61, 122, 244

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 838,515,721,244, is 1.

Now, the common factors can be found like this.

838:2x 419

515:5x 103

721:7x 103

244:2x 2x 61

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

2x 103 = 206

Therefore, the value for common factors is 206.

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 = 75923520680/(1x206)

LCM = 75923520680/206

LCM = 368560780

Thus, we can understand that the LCM of 838,515,721,244 is 368560780.
