Given numbers are 214,966,920,721

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

The LCM of 214,966,920,721 is 212925720.

Find LCM of 214,966,920,721 with Prime Factorization

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

2 x 7 x 23 x 107 x 3 x 20 x 103 = 212925720

Therefore, the lowest common multiple of 214,966,920,721 is 212925720.

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.

214 x 966 x 920 x 721 = 137124163680

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.

214 : 1, 2, 107, 214

966 : 1, 2, 3, 6, 7, 14, 21, 23, 42, 46, 69, 138, 161, 322, 483, 966

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

721 : 1, 7, 103, 721

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 214,966,920,721, is 1.

Now, the common factors can be found like this.

214:2x 107

966:2x 3x 7x 23

920:2x 2x 2x 5x 23

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 23 = 644

Therefore, the value for common factors is 644.

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 = 137124163680/(1x644)

LCM = 137124163680/644

LCM = 212925720

Thus, we can understand that the LCM of 214,966,920,721 is 212925720.
