Given numbers are 711,618,818,421

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

The LCM of 711,618,818,421 is 25219834074.

Find LCM of 711,618,818,421 with Prime Factorization

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

2 x 3 x 237 x 103 x 409 x 421 = 25219834074

Therefore, the lowest common multiple of 711,618,818,421 is 25219834074.

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.

711 x 618 x 818 x 421 = 151319004444

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.

711 : 1, 3, 9, 79, 237, 711

618 : 1, 2, 3, 6, 103, 206, 309, 618

818 : 1, 2, 409, 818

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 711,618,818,421, is 1.

Now, the common factors can be found like this.

711:3x 3x 79

618:2x 3x 103

818:2x 409

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.

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 151319004444/(1x6)

LCM = 151319004444/6

LCM = 25219834074

Thus, we can understand that the LCM of 711,618,818,421 is 25219834074.
