Calculate the LCM of 616,758,394,462

Given numbers are 616,758,394,462

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

The LCM of 616,758,394,462 is 137977224.

Find LCM of 616,758,394,462 with Prime Factorization


2 616, 758, 394, 462
7 308, 379, 197, 231
11 44, 379, 197, 33
4, 379, 197, 3

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

2 x 7 x 11 x 4 x 379 x 197 x 3 = 137977224

Therefore, the lowest common multiple of 616,758,394,462 is 137977224.

LCM Formula to Find Lowest Common Multiple of 616,758,394,462

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.

616 x 758 x 394 x 462 = 84993969984

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.

616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616

758 : 1, 2, 379, 758

394 : 1, 2, 197, 394

462 : 1, 2, 3, 6, 7, 11, 14, 21, 22, 33, 42, 66, 77, 154, 231, 462

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 616,758,394,462, is 2.

Now, the common factors can be found like this.

616:2x 2x 2x 7x 11

758:2x 379

394:2x 197

462:2x 3x 7x 11

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 7x 11 = 308

Therefore, the value for common factors is 308.

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 = 84993969984/(2x308)

LCM = 84993969984/616

LCM = 137977224

Thus, we can understand that the LCM of 616,758,394,462 is 137977224.
