Given numbers are 685,526,136,221

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

The LCM of 685,526,136,221 is 318514040.

Find LCM of 685,526,136,221 with Prime Factorization

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

2 x 17 x 685 x 263 x 4 x 13 = 318514040

Therefore, the lowest common multiple of 685,526,136,221 is 318514040.

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 526 x 136 x 221 = 10829477360

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

526 : 1, 2, 263, 526

136 : 1, 2, 4, 8, 17, 34, 68, 136

221 : 1, 13, 17, 221

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 685,526,136,221, is 1.

Now, the common factors can be found like this.

685:5x 137

526:2x 263

136:2x 2x 2x 17

221:13x 17

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 17 = 34

Therefore, the value for common factors is 34.

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 = 10829477360/(1x34)

LCM = 10829477360/34

LCM = 318514040

Thus, we can understand that the LCM of 685,526,136,221 is 318514040.
