Given numbers are 303,707,705,421

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

The LCM of 303,707,705,421 is 209841135.

Find LCM of 303,707,705,421 with Prime Factorization

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

3 x 101 x 1 x 7 x 235 x 421 = 209841135

Therefore, the lowest common multiple of 303,707,705,421 is 209841135.

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.

303 x 707 x 705 x 421 = 63581863905

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.

303 : 1, 3, 101, 303

707 : 1, 7, 101, 707

705 : 1, 3, 5, 15, 47, 141, 235, 705

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 303,707,705,421, is 1.

Now, the common factors can be found like this.

303:3x 101

707:7x 101

705:3x 5x 47

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.

3x 101 = 303

Therefore, the value for common factors is 303.

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 = 63581863905/(1x303)

LCM = 63581863905/303

LCM = 209841135

Thus, we can understand that the LCM of 303,707,705,421 is 209841135.
