Given numbers are 781,994,193,304

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

The LCM of 781,994,193,304 is 320759824.

Find LCM of 781,994,193,304 with Prime Factorization

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

2 x 71 x 11 x 7 x 193 x 152 = 320759824

Therefore, the lowest common multiple of 781,994,193,304 is 320759824.

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.

781 x 994 x 193 x 304 = 45547895008

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.

781 : 1, 11, 71, 781

994 : 1, 2, 7, 14, 71, 142, 497, 994

193 : 1, 193

304 : 1, 2, 4, 8, 16, 19, 38, 76, 152, 304

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,994,193,304, is 1.

Now, the common factors can be found like this.

781:11x 71

994:2x 7x 71

193:193

304:2x 2x 2x 2x 19

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

2x 71 = 142

Therefore, the value for common factors is 142.

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 = 45547895008/(1x142)

LCM = 45547895008/142

LCM = 320759824

Thus, we can understand that the LCM of 781,994,193,304 is 320759824.
