Given numbers are 860,165,690,765,721

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

The LCM of 860,165,690,765,721 is 24001902540.

Find LCM of 860,165,690,765,721 with Prime Factorization

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

2 x 3 x 5 x 86 x 11 x 23 x 51 x 721 = 24001902540

Therefore, the lowest common multiple of 860,165,690,765,721 is 24001902540.

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.

860 x 165 x 690 x 765 x 721 = 54004280715000

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.

860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860

165 : 1, 3, 5, 11, 15, 33, 55, 165

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765

721 : 1, 7, 103, 721

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 860,165,690,765,721, is 1.

Now, the common factors can be found like this.

860:2x 2x 5x 43

165:3x 5x 11

690:2x 3x 5x 23

765:3x 3x 5x 17

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 3x 3x 5x 5x 5 = 2250

Therefore, the value for common factors is 2250.

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 = 54004280715000/(1x2250)

LCM = 54004280715000/2250

LCM = 24001902540

Thus, we can understand that the LCM of 860,165,690,765,721 is 24001902540.
