Given numbers are 721,711,771,523

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

The LCM of 721,711,771,523 is 68903245341.

Find LCM of 721,711,771,523 with Prime Factorization

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

3 x 721 x 237 x 257 x 523 = 68903245341

Therefore, the lowest common multiple of 721,711,771,523 is 68903245341.

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.

721 x 711 x 771 x 523 = 206709736023

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.

721 : 1, 7, 103, 721

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

771 : 1, 3, 257, 771

523 : 1, 523

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,711,771,523, is 1.

Now, the common factors can be found like this.

721:7x 103

711:3x 3x 79

771:3x 257

523:523

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 = 206709736023/(1x3)

LCM = 206709736023/3

LCM = 68903245341

Thus, we can understand that the LCM of 721,711,771,523 is 68903245341.
