Given numbers are 247,213,746,940

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

The LCM of 247,213,746,940 is 18446468820.

Find LCM of 247,213,746,940 with Prime Factorization

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

2 x 247 x 213 x 373 x 470 = 18446468820

Therefore, the lowest common multiple of 247,213,746,940 is 18446468820.

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 213 x 746 x 940 = 36892937640

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

213 : 1, 3, 71, 213

746 : 1, 2, 373, 746

940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 247,213,746,940, is 1.

Now, the common factors can be found like this.

247:13x 19

213:3x 71

746:2x 373

940:2x 2x 5x 47

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

2 = 2

Therefore, the value for common factors is 2.

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 = 36892937640/(1x2)

LCM = 36892937640/2

LCM = 18446468820

Thus, we can understand that the LCM of 247,213,746,940 is 18446468820.
