Given numbers are 685,278,973,184

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

The LCM of 685,278,973,184 is 122636920.

Find LCM of 685,278,973,184 with Prime Factorization

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

2 x 139 x 685 x 1 x 7 x 92 = 122636920

Therefore, the lowest common multiple of 685,278,973,184 is 122636920.

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 278 x 973 x 184 = 34093063760

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

278 : 1, 2, 139, 278

973 : 1, 7, 139, 973

184 : 1, 2, 4, 8, 23, 46, 92, 184

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 685,278,973,184, is 1.

Now, the common factors can be found like this.

685:5x 137

278:2x 139

973:7x 139

184:2x 2x 2x 23

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

2x 139 = 278

Therefore, the value for common factors is 278.

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 = 34093063760/(1x278)

LCM = 34093063760/278

LCM = 122636920

Thus, we can understand that the LCM of 685,278,973,184 is 122636920.
