Given numbers are 142,860,682,644

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

The LCM of 142,860,682,644 is 3352255060.

Find LCM of 142,860,682,644 with Prime Factorization

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

2 x 2 x 71 x 215 x 341 x 161 = 3352255060

Therefore, the lowest common multiple of 142,860,682,644 is 3352255060.

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.

142 x 860 x 682 x 644 = 53636080960

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.

142 : 1, 2, 71, 142

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

682 : 1, 2, 11, 22, 31, 62, 341, 682

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 142,860,682,644, is 2.

Now, the common factors can be found like this.

142:2x 71

860:2x 2x 5x 43

682:2x 11x 31

644:2x 2x 7x 23

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 2 = 8

Therefore, the value for common factors is 8.

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 = 53636080960/(2x8)

LCM = 53636080960/16

LCM = 3352255060

Thus, we can understand that the LCM of 142,860,682,644 is 3352255060.
