The LCM of 243,156,949,278 is 128217492.

Find LCM of 243,156,949,278 with Prime Factorization


2 243, 156, 949, 278
3 243, 78, 949, 139
13 81, 26, 949, 139
81, 2, 73, 139

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

2 x 3 x 13 x 81 x 2 x 73 x 139 = 128217492

Therefore, the lowest common multiple of 243,156,949,278 is 128217492.

LCM Formula to Find Lowest Common Multiple of 243,156,949,278

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.

243 x 156 x 949 x 278 = 10000964376

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.

243 : 1, 3, 9, 27, 81, 243

156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156

949 : 1, 13, 73, 949

278 : 1, 2, 139, 278

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 243,156,949,278, is 1.

Now, the common factors can be found like this.

243:3x 3x 3x 3x 3

156:2x 2x 3x 13

949:13x 73

278:2x 139

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 13 = 78

Therefore, the value for common factors is 78.

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 = 10000964376/(1x78)

LCM = 10000964376/78

LCM = 128217492

Thus, we can understand that the LCM of 243,156,949,278 is 128217492.
