Given numbers are 685,338,130,97

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

The LCM of 685,338,130,97 is 22458410.

Find LCM of 685,338,130,97 with Prime Factorization

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

2 x 5 x 13 x 137 x 1 x 13 x 97 = 22458410

Therefore, the lowest common multiple of 685,338,130,97 is 22458410.

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 338 x 130 x 97 = 2919593300

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

338 : 1, 2, 13, 26, 169, 338

130 : 1, 2, 5, 10, 13, 26, 65, 130

97 : 1, 97

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 685,338,130,97, is 1.

Now, the common factors can be found like this.

685:5x 137

338:2x 13x 13

130:2x 5x 13

97:97

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

2x 5x 13 = 130

Therefore, the value for common factors is 130.

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 = 2919593300/(1x130)

LCM = 2919593300/130

LCM = 22458410

Thus, we can understand that the LCM of 685,338,130,97 is 22458410.
