Given numbers are 247,538,946,974

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

The LCM of 247,538,946,974 is 30610422986.

Find LCM of 247,538,946,974 with Prime Factorization

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

2 x 247 x 269 x 473 x 487 = 30610422986

Therefore, the lowest common multiple of 247,538,946,974 is 30610422986.

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 538 x 946 x 974 = 122441691944

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

538 : 1, 2, 269, 538

946 : 1, 2, 11, 22, 43, 86, 473, 946

974 : 1, 2, 487, 974

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 247,538,946,974, is 1.

Now, the common factors can be found like this.

247:13x 19

538:2x 269

946:2x 11x 43

974:2x 487

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 122441691944/(1x4)

LCM = 122441691944/4

LCM = 30610422986

Thus, we can understand that the LCM of 247,538,946,974 is 30610422986.
