Given numbers are 689,562,972

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

The LCM of 689,562,972 is 188187948.

Find LCM of 689,562,972 with Prime Factorization

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

2 x 689 x 281 x 486 = 188187948

Therefore, the lowest common multiple of 689,562,972 is 188187948.

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.

689 x 562 x 972 = 376375896

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.

689 : 1, 13, 53, 689

562 : 1, 2, 281, 562

972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,562,972, is 1.

Now, the common factors can be found like this.

689:13x 53

562:2x 281

972:2x 2x 3x 3x 3x 3x 3

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

2 = 2

Therefore, the value for common factors is 2.

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 = 376375896/(1x2)

LCM = 376375896/2

LCM = 188187948

Thus, we can understand that the LCM of 689,562,972 is 188187948.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 860, 665, 229
