Given numbers are 689,983,742

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

The LCM of 689,983,742 is 9482018.

Find LCM of 689,983,742 with Prime Factorization

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

53 x 13 x 983 x 14 = 9482018

Therefore, the lowest common multiple of 689,983,742 is 9482018.

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 983 x 742 = 502546954

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

983 : 1, 983

742 : 1, 2, 7, 14, 53, 106, 371, 742

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,983,742, is 1.

Now, the common factors can be found like this.

689:13x 53

983:983

742:2x 7x 53

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

53 = 53

Therefore, the value for common factors is 53.

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 = 502546954/(1x53)

LCM = 502546954/53

LCM = 9482018

Thus, we can understand that the LCM of 689,983,742 is 9482018.

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

• LCM of 739, 517, 755
• LCM of 805, 976, 506
