Calculate the LCM of 645,793,463,690,170

Given numbers are 645,793,463,690,170

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

The LCM of 645,793,463,690,170 is 185191328010.

Find LCM of 645,793,463,690,170 with Prime Factorization


2 645, 793, 463, 690, 170
3 645, 793, 463, 345, 85
5 215, 793, 463, 115, 85
43, 793, 463, 23, 17

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

2 x 3 x 5 x 43 x 793 x 463 x 23 x 17 = 185191328010

Therefore, the lowest common multiple of 645,793,463,690,170 is 185191328010.

LCM Formula to Find Lowest Common Multiple of 645,793,463,690,170

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.

645 x 793 x 463 x 690 x 170 = 27778699201500

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.

645 : 1, 3, 5, 15, 43, 129, 215, 645

793 : 1, 13, 61, 793

463 : 1, 463

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

170 : 1, 2, 5, 10, 17, 34, 85, 170

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 645,793,463,690,170, is 1.

Now, the common factors can be found like this.

645:3x 5x 43

793:13x 61

463:463

690:2x 3x 5x 23

170:2x 5x 17

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 5x 5 = 150

Therefore, the value for common factors is 150.

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 = 27778699201500/(1x150)

LCM = 27778699201500/150

LCM = 185191328010

Thus, we can understand that the LCM of 645,793,463,690,170 is 185191328010.
