Given numbers are 789,669,407

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

The LCM of 789,669,407 is 71610429.

Find LCM of 789,669,407 with Prime Factorization

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

3 x 263 x 223 x 407 = 71610429

Therefore, the lowest common multiple of 789,669,407 is 71610429.

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.

789 x 669 x 407 = 214831287

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.

789 : 1, 3, 263, 789

669 : 1, 3, 223, 669

407 : 1, 11, 37, 407

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 789,669,407, is 1.

Now, the common factors can be found like this.

789:3x 263

669:3x 223

407:11x 37

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

3 = 3

Therefore, the value for common factors is 3.

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 = 214831287/(1x3)

LCM = 214831287/3

LCM = 71610429

Thus, we can understand that the LCM of 789,669,407 is 71610429.

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

• LCM of 601, 888, 103
