Given numbers are 681,454,434,778

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

The LCM of 681,454,434,778 is 114970506.

Find LCM of 681,454,434,778 with Prime Factorization

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

2 x 227 x 3 x 1 x 217 x 389 = 114970506

Therefore, the lowest common multiple of 681,454,434,778 is 114970506.

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.

681 x 454 x 434 x 778 = 104393219448

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.

681 : 1, 3, 227, 681

454 : 1, 2, 227, 454

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

778 : 1, 2, 389, 778

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 681,454,434,778, is 1.

Now, the common factors can be found like this.

681:3x 227

454:2x 227

434:2x 7x 31

778:2x 389

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 227 = 908

Therefore, the value for common factors is 908.

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 = 104393219448/(1x908)

LCM = 104393219448/908

LCM = 114970506

Thus, we can understand that the LCM of 681,454,434,778 is 114970506.
