Given numbers are 982,425,686,642

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

The LCM of 982,425,686,642 is 45951487050.

Find LCM of 982,425,686,642 with Prime Factorization

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

2 x 491 x 425 x 343 x 321 = 45951487050

Therefore, the lowest common multiple of 982,425,686,642 is 45951487050.

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.

982 x 425 x 686 x 642 = 183805948200

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.

982 : 1, 2, 491, 982

425 : 1, 5, 17, 25, 85, 425

686 : 1, 2, 7, 14, 49, 98, 343, 686

642 : 1, 2, 3, 6, 107, 214, 321, 642

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 982,425,686,642, is 1.

Now, the common factors can be found like this.

982:2x 491

425:5x 5x 17

686:2x 7x 7x 7

642:2x 3x 107

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 183805948200/(1x4)

LCM = 183805948200/4

LCM = 45951487050

Thus, we can understand that the LCM of 982,425,686,642 is 45951487050.
