Given numbers are 247,978,115,198

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

The LCM of 247,978,115,198 is 916742970.

Find LCM of 247,978,115,198 with Prime Factorization

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

2 x 3 x 247 x 163 x 115 x 33 = 916742970

Therefore, the lowest common multiple of 247,978,115,198 is 916742970.

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.

247 x 978 x 115 x 198 = 5500457820

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.

247 : 1, 13, 19, 247

978 : 1, 2, 3, 6, 163, 326, 489, 978

115 : 1, 5, 23, 115

198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 247,978,115,198, is 1.

Now, the common factors can be found like this.

247:13x 19

978:2x 3x 163

115:5x 23

198:2x 3x 3x 11

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 5500457820/(1x6)

LCM = 5500457820/6

LCM = 916742970

Thus, we can understand that the LCM of 247,978,115,198 is 916742970.
