Given numbers are 771,785,260,641

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

The LCM of 771,785,260,641 is 20173693020.

Find LCM of 771,785,260,641 with Prime Factorization

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

5 x 771 x 157 x 52 x 641 = 20173693020

Therefore, the lowest common multiple of 771,785,260,641 is 20173693020.

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.

771 x 785 x 260 x 641 = 100868465100

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.

771 : 1, 3, 257, 771

785 : 1, 5, 157, 785

260 : 1, 2, 4, 5, 10, 13, 20, 26, 52, 65, 130, 260

641 : 1, 641

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 771,785,260,641, is 1.

Now, the common factors can be found like this.

771:3x 257

785:5x 157

260:2x 2x 5x 13

641:641

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

5 = 5

Therefore, the value for common factors is 5.

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 = 100868465100/(1x5)

LCM = 100868465100/5

LCM = 20173693020

Thus, we can understand that the LCM of 771,785,260,641 is 20173693020.
