Calculate the LCM of 493,609,651,645

Given numbers are 493,609,651,645

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

The LCM of 493,609,651,645 is 69002745.

Find LCM of 493,609,651,645 with Prime Factorization


3 493, 609, 651, 645
7 493, 203, 217, 215
29 493, 29, 31, 215
17, 1, 31, 215

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

3 x 7 x 29 x 17 x 1 x 31 x 215 = 69002745

Therefore, the lowest common multiple of 493,609,651,645 is 69002745.

LCM Formula to Find Lowest Common Multiple of 493,609,651,645

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.

493 x 609 x 651 x 645 = 126068015115

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.

493 : 1, 17, 29, 493

609 : 1, 3, 7, 21, 29, 87, 203, 609

651 : 1, 3, 7, 21, 31, 93, 217, 651

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 493,609,651,645, is 1.

Now, the common factors can be found like this.

493:17x 29

609:3x 7x 29

651:3x 7x 31

645:3x 5x 43

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

3x 3x 7x 29 = 1827

Therefore, the value for common factors is 1827.

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 = 126068015115/(1x1827)

LCM = 126068015115/1827

LCM = 69002745

Thus, we can understand that the LCM of 493,609,651,645 is 69002745.
