Find LCM of 378,249,466,938,861 with Prime Factorization


2 378, 249, 466, 938, 861
3 189, 249, 233, 469, 861
7 63, 83, 233, 469, 287
9, 83, 233, 67, 41

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

2 x 3 x 7 x 9 x 83 x 233 x 67 x 41 = 20080960074

Therefore, the lowest common multiple of 378,249,466,938,861 is 20080960074.

LCM Formula to Find Lowest Common Multiple of 378,249,466,938,861

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.

378 x 249 x 466 x 938 x 861 = 35422813570536

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.

378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378

249 : 1, 3, 83, 249

466 : 1, 2, 233, 466

938 : 1, 2, 7, 14, 67, 134, 469, 938

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 378,249,466,938,861, is 1.

Now, the common factors can be found like this.

378:2x 3x 3x 3x 7

249:3x 83

466:2x 233

938:2x 7x 67

861:3x 7x 41

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 7x 7 = 1764

Therefore, the value for common factors is 1764.

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 = 35422813570536/(1x1764)

LCM = 35422813570536/1764

LCM = 20080960074

Thus, we can understand that the LCM of 378,249,466,938,861 is 20080960074.
