Given numbers are 182,862,420,721

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

The LCM of 182,862,420,721 is 242385780.

Find LCM of 182,862,420,721 with Prime Factorization

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

2 x 7 x 13 x 431 x 30 x 103 = 242385780

Therefore, the lowest common multiple of 182,862,420,721 is 242385780.

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.

182 x 862 x 420 x 721 = 47507612880

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.

182 : 1, 2, 7, 13, 14, 26, 91, 182

862 : 1, 2, 431, 862

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

721 : 1, 7, 103, 721

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 182,862,420,721, is 1.

Now, the common factors can be found like this.

182:2x 7x 13

862:2x 431

420:2x 2x 3x 5x 7

721:7x 103

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

2x 2x 7x 7 = 196

Therefore, the value for common factors is 196.

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 = 47507612880/(1x196)

LCM = 47507612880/196

LCM = 242385780

Thus, we can understand that the LCM of 182,862,420,721 is 242385780.
