Calculate the LCM of 642,642,203,180

Given numbers are 642,642,203,180

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

The LCM of 642,642,203,180 is 3909780.

Find LCM of 642,642,203,180 with Prime Factorization

2	642, 642, 203, 180
3	321, 321, 203, 90
107	107, 107, 203, 30
	1, 1, 203, 30

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

2 x 3 x 107 x 1 x 1 x 203 x 30 = 3909780

LCM Formula to Find Lowest Common Multiple of 642,642,203,180

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.

642 x 642 x 203 x 180 = 15060472560

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.

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

203 : 1, 7, 29, 203

180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,642,203,180, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

203:7x 29

180:2x 2x 3x 3x 5

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 3x 3x 107 = 3852

Therefore, the value for common factors is 3852.

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 = 15060472560/(1x3852)

LCM = 15060472560/3852

LCM = 3909780

Thus, we can understand that the LCM of 642,642,203,180 is 3909780.
