Given numbers are 798,238,434,720

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

The LCM of 798,238,434,720 is 50465520.

Find LCM of 798,238,434,720 with Prime Factorization

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

2 x 3 x 7 x 19 x 17 x 31 x 120 = 50465520

Therefore, the lowest common multiple of 798,238,434,720 is 50465520.

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.

798 x 238 x 434 x 720 = 59347451520

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.

798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798

238 : 1, 2, 7, 14, 17, 34, 119, 238

434 : 1, 2, 7, 14, 31, 62, 217, 434

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 798,238,434,720, is 2.

Now, the common factors can be found like this.

798:2x 3x 7x 19

238:2x 7x 17

434:2x 7x 31

720:2x 2x 2x 2x 3x 3x 5

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

2x 2x 3x 7x 7 = 588

Therefore, the value for common factors is 588.

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 = 59347451520/(2x588)

LCM = 59347451520/1176

LCM = 50465520

Thus, we can understand that the LCM of 798,238,434,720 is 50465520.
