Calculate the LCM of 685,643,908,462

Given numbers are 685,643,908,462

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

The LCM of 685,643,908,462 is 92384555340.

Find LCM of 685,643,908,462 with Prime Factorization


2 685, 643, 908, 462
685, 643, 454, 231

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

2 x 685 x 643 x 454 x 231 = 92384555340

Therefore, the lowest common multiple of 685,643,908,462 is 92384555340.

LCM Formula to Find Lowest Common Multiple of 685,643,908,462

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.

685 x 643 x 908 x 462 = 184769110680

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.

685 : 1, 5, 137, 685

643 : 1, 643

908 : 1, 2, 4, 227, 454, 908

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 685,643,908,462, is 1.

Now, the common factors can be found like this.

685:5x 137

643:643

908:2x 2x 227

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.

2 = 2

Therefore, the value for common factors is 2.

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 = 184769110680/(1x2)

LCM = 184769110680/2

LCM = 92384555340

Thus, we can understand that the LCM of 685,643,908,462 is 92384555340.
