Given numbers are 247,169,287,369

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

The LCM of 247,169,287,369 is 8294013.

Find LCM of 247,169,287,369 with Prime Factorization

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

13 x 41 x 19 x 13 x 7 x 9 = 8294013

Therefore, the lowest common multiple of 247,169,287,369 is 8294013.

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 169 x 287 x 369 = 4420708929

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

169 : 1, 13, 169

287 : 1, 7, 41, 287

369 : 1, 3, 9, 41, 123, 369

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 247,169,287,369, is 1.

Now, the common factors can be found like this.

247:13x 19

169:13x 13

287:7x 41

369:3x 3x 41

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

13x 41 = 533

Therefore, the value for common factors is 533.

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 = 4420708929/(1x533)

LCM = 4420708929/533

LCM = 8294013

Thus, we can understand that the LCM of 247,169,287,369 is 8294013.
