Given numbers are 707,707,421

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

The LCM of 707,707,421 is 297647.

Find LCM of 707,707,421 with Prime Factorization

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

7 x 101 x 1 x 1 x 421 = 297647

Therefore, the lowest common multiple of 707,707,421 is 297647.

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.

707 x 707 x 421 = 210436429

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.

707 : 1, 7, 101, 707

707 : 1, 7, 101, 707

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 707,707,421, is 1.

Now, the common factors can be found like this.

707:7x 101

707:7x 101

421:421

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

7x 101 = 707

Therefore, the value for common factors is 707.

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 = 210436429/(1x707)

LCM = 210436429/707

LCM = 297647

Thus, we can understand that the LCM of 707,707,421 is 297647.

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

• LCM of 870, 263, 963
• LCM of 789, 102, 756
