Given numbers are 451,209,789

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

The LCM of 451,209,789 is 6760941.

Find LCM of 451,209,789 with Prime Factorization

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

11 x 41 x 19 x 789 = 6760941

Therefore, the lowest common multiple of 451,209,789 is 6760941.

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.

451 x 209 x 789 = 74370351

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.

451 : 1, 11, 41, 451

209 : 1, 11, 19, 209

789 : 1, 3, 263, 789

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 451,209,789, is 1.

Now, the common factors can be found like this.

451:11x 41

209:11x 19

789:3x 263

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

11 = 11

Therefore, the value for common factors is 11.

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 = 74370351/(1x11)

LCM = 74370351/11

LCM = 6760941

Thus, we can understand that the LCM of 451,209,789 is 6760941.

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

• LCM of 690, 174, 558
• LCM of 609, 984, 104
