Given numbers are 867,692,188,689

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

The LCM of 867,692,188,689 is 19428634212.

Find LCM of 867,692,188,689 with Prime Factorization

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

2 x 2 x 867 x 173 x 47 x 689 = 19428634212

Therefore, the lowest common multiple of 867,692,188,689 is 19428634212.

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.

867 x 692 x 188 x 689 = 77714536848

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.

867 : 1, 3, 17, 51, 289, 867

692 : 1, 2, 4, 173, 346, 692

188 : 1, 2, 4, 47, 94, 188

689 : 1, 13, 53, 689

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 867,692,188,689, is 1.

Now, the common factors can be found like this.

867:3x 17x 17

692:2x 2x 173

188:2x 2x 47

689:13x 53

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 77714536848/(1x4)

LCM = 77714536848/4

LCM = 19428634212

Thus, we can understand that the LCM of 867,692,188,689 is 19428634212.
