Calculate the LCM of 684,855,603,651

Given numbers are 684,855,603,651

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

The LCM of 684,855,603,651 is 49723380.

Find LCM of 684,855,603,651 with Prime Factorization


3 684, 855, 603, 651
3 228, 285, 201, 217
19 76, 95, 67, 217
4, 5, 67, 217

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

3 x 3 x 19 x 4 x 5 x 67 x 217 = 49723380

Therefore, the lowest common multiple of 684,855,603,651 is 49723380.

LCM Formula to Find Lowest Common Multiple of 684,855,603,651

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.

684 x 855 x 603 x 651 = 229572845460

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.

684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684

855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855

603 : 1, 3, 9, 67, 201, 603

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

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 684,855,603,651, is 3.

Now, the common factors can be found like this.

684:2x 2x 3x 3x 19

855:3x 3x 5x 19

603:3x 3x 67

651:3x 7x 31

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 3x 3x 19 = 1539

Therefore, the value for common factors is 1539.

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 = 229572845460/(3x1539)

LCM = 229572845460/4617

LCM = 49723380

Thus, we can understand that the LCM of 684,855,603,651 is 49723380.
