Given numbers are 771,485,686,642,776

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

The LCM of 771,485,686,642,776 is 109790307480.

Find LCM of 771,485,686,642,776 with Prime Factorization

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

2 x 3 x 97 x 257 x 5 x 343 x 107 x 4 = 109790307480

Therefore, the lowest common multiple of 771,485,686,642,776 is 109790307480.

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 485 x 686 x 642 x 776 = 127795917906720

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

485 : 1, 5, 97, 485

686 : 1, 2, 7, 14, 49, 98, 343, 686

642 : 1, 2, 3, 6, 107, 214, 321, 642

776 : 1, 2, 4, 8, 97, 194, 388, 776

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 771,485,686,642,776, is 1.

Now, the common factors can be found like this.

771:3x 257

485:5x 97

686:2x 7x 7x 7

642:2x 3x 107

776:2x 2x 2x 97

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

2x 2x 3x 97 = 1164

Therefore, the value for common factors is 1164.

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 = 127795917906720/(1x1164)

LCM = 127795917906720/1164

LCM = 109790307480

Thus, we can understand that the LCM of 771,485,686,642,776 is 109790307480.
