Given numbers are 685,708,872,956

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

The LCM of 685,708,872,956 is 25268427960.

Find LCM of 685,708,872,956 with Prime Factorization

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

2 x 2 x 685 x 177 x 218 x 239 = 25268427960

Therefore, the lowest common multiple of 685,708,872,956 is 25268427960.

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 708 x 872 x 956 = 404294847360

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

708 : 1, 2, 3, 4, 6, 12, 59, 118, 177, 236, 354, 708

872 : 1, 2, 4, 8, 109, 218, 436, 872

956 : 1, 2, 4, 239, 478, 956

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 685,708,872,956, is 1.

Now, the common factors can be found like this.

685:5x 137

708:2x 2x 3x 59

872:2x 2x 2x 109

956:2x 2x 239

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 2x 2 = 16

Therefore, the value for common factors is 16.

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 = 404294847360/(1x16)

LCM = 404294847360/16

LCM = 25268427960

Thus, we can understand that the LCM of 685,708,872,956 is 25268427960.
