Given numbers are 247,437,161,253

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

The LCM of 247,437,161,253 is 437437.

Find LCM of 247,437,161,253 with Prime Factorization

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

19 x 23 x 13 x 1 x 7 x 11 = 437437

Therefore, the lowest common multiple of 247,437,161,253 is 437437.

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 437 x 161 x 253 = 4396679287

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

437 : 1, 19, 23, 437

161 : 1, 7, 23, 161

253 : 1, 11, 23, 253

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 247,437,161,253, is 1.

Now, the common factors can be found like this.

247:13x 19

437:19x 23

161:7x 23

253:11x 23

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

19x 23x 23 = 10051

Therefore, the value for common factors is 10051.

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 = 4396679287/(1x10051)

LCM = 4396679287/10051

LCM = 437437

Thus, we can understand that the LCM of 247,437,161,253 is 437437.
