Given numbers are 242,403,639,871

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

The LCM of 242,403,639,871 is 4175380638.

Find LCM of 242,403,639,871 with Prime Factorization

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

13 x 242 x 31 x 639 x 67 = 4175380638

Therefore, the lowest common multiple of 242,403,639,871 is 4175380638.

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.

242 x 403 x 639 x 871 = 54279948294

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.

242 : 1, 2, 11, 22, 121, 242

403 : 1, 13, 31, 403

639 : 1, 3, 9, 71, 213, 639

871 : 1, 13, 67, 871

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 242,403,639,871, is 1.

Now, the common factors can be found like this.

242:2x 11x 11

403:13x 31

639:3x 3x 71

871:13x 67

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

13 = 13

Therefore, the value for common factors is 13.

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 = 54279948294/(1x13)

LCM = 54279948294/13

LCM = 4175380638

Thus, we can understand that the LCM of 242,403,639,871 is 4175380638.
