Given numbers are 778,509,907,434

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

The LCM of 778,509,907,434 is 77940717638.

Find LCM of 778,509,907,434 with Prime Factorization

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

2 x 389 x 509 x 907 x 217 = 77940717638

Therefore, the lowest common multiple of 778,509,907,434 is 77940717638.

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.

778 x 509 x 907 x 434 = 155881435276

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.

778 : 1, 2, 389, 778

509 : 1, 509

907 : 1, 907

434 : 1, 2, 7, 14, 31, 62, 217, 434

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 778,509,907,434, is 1.

Now, the common factors can be found like this.

778:2x 389

509:509

907:907

434:2x 7x 31

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

2 = 2

Therefore, the value for common factors is 2.

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 = 155881435276/(1x2)

LCM = 155881435276/2

LCM = 77940717638

Thus, we can understand that the LCM of 778,509,907,434 is 77940717638.
