Given numbers are 853,214,781,438

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

The LCM of 853,214,781,438 is 31221801138.

Find LCM of 853,214,781,438 with Prime Factorization

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

2 x 853 x 107 x 781 x 219 = 31221801138

Therefore, the lowest common multiple of 853,214,781,438 is 31221801138.

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.

853 x 214 x 781 x 438 = 62443602276

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.

853 : 1, 853

214 : 1, 2, 107, 214

781 : 1, 11, 71, 781

438 : 1, 2, 3, 6, 73, 146, 219, 438

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 853,214,781,438, is 1.

Now, the common factors can be found like this.

853:853

214:2x 107

781:11x 71

438:2x 3x 73

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 = 62443602276/(1x2)

LCM = 62443602276/2

LCM = 31221801138

Thus, we can understand that the LCM of 853,214,781,438 is 31221801138.
