Given numbers are 7,711,641,561

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

The LCM of 7,711,641,561 is 596578059.

Find LCM of 7,711,641,561 with Prime Factorization

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

3 x 7 x 237 x 641 x 187 = 596578059

Therefore, the lowest common multiple of 7,711,641,561 is 596578059.

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.

7 x 711 x 641 x 561 = 1789734177

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.

7 : 1, 7

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

641 : 1, 641

561 : 1, 3, 11, 17, 33, 51, 187, 561

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 7,711,641,561, is 1.

Now, the common factors can be found like this.

7:7

711:3x 3x 79

641:641

561:3x 11x 17

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 = 1789734177/(1x3)

LCM = 1789734177/3

LCM = 596578059

Thus, we can understand that the LCM of 7,711,641,561 is 596578059.
