The LCM of 137,684,628,394 is 2898294732.

Find LCM of 137,684,628,394 with Prime Factorization


2 137, 684, 628, 394
2 137, 342, 314, 197
137, 171, 157, 197

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

2 x 2 x 137 x 171 x 157 x 197 = 2898294732

Therefore, the lowest common multiple of 137,684,628,394 is 2898294732.

LCM Formula to Find Lowest Common Multiple of 137,684,628,394

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.

137 x 684 x 628 x 394 = 23186357856

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.

137 : 1, 137

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

628 : 1, 2, 4, 157, 314, 628

394 : 1, 2, 197, 394

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 137,684,628,394, is 1.

Now, the common factors can be found like this.

137:137

684:2x 2x 3x 3x 19

628:2x 2x 157

394:2x 197

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 2 = 8

Therefore, the value for common factors is 8.

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 = 23186357856/(1x8)

LCM = 23186357856/8

LCM = 2898294732

Thus, we can understand that the LCM of 137,684,628,394 is 2898294732.
