Calculate the LCM of 394,861,813,820,469

Given numbers are 394,861,813,820,469

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

The LCM of 394,861,813,820,469 is 61594717380.

Find LCM of 394,861,813,820,469 with Prime Factorization


2 394, 861, 813, 820, 469
3 197, 861, 813, 410, 469
7 197, 287, 271, 410, 469
41 197, 41, 271, 410, 67
197, 1, 271, 10, 67

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

2 x 3 x 7 x 41 x 197 x 1 x 271 x 10 x 67 = 61594717380

Therefore, the lowest common multiple of 394,861,813,820,469 is 61594717380.

LCM Formula to Find Lowest Common Multiple of 394,861,813,820,469

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.

394 x 861 x 813 x 820 x 469 = 106066103328360

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.

394 : 1, 2, 197, 394

861 : 1, 3, 7, 21, 41, 123, 287, 861

813 : 1, 3, 271, 813

820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820

469 : 1, 7, 67, 469

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 394,861,813,820,469, is 1.

Now, the common factors can be found like this.

394:2x 197

861:3x 7x 41

813:3x 271

820:2x 2x 5x 41

469:7x 67

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 7x 41 = 1722

Therefore, the value for common factors is 1722.

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 = 106066103328360/(1x1722)

LCM = 106066103328360/1722

LCM = 61594717380

Thus, we can understand that the LCM of 394,861,813,820,469 is 61594717380.
