Given numbers are 681,452,862,578

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

The LCM of 681,452,862,578 is 38340754908.

Find LCM of 681,452,862,578 with Prime Factorization

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

2 x 681 x 226 x 431 x 289 = 38340754908

Therefore, the lowest common multiple of 681,452,862,578 is 38340754908.

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 452 x 862 x 578 = 153363019632

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

452 : 1, 2, 4, 113, 226, 452

862 : 1, 2, 431, 862

578 : 1, 2, 17, 34, 289, 578

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 681,452,862,578, is 1.

Now, the common factors can be found like this.

681:3x 227

452:2x 2x 113

862:2x 431

578:2x 17x 17

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 153363019632/(1x4)

LCM = 153363019632/4

LCM = 38340754908

Thus, we can understand that the LCM of 681,452,862,578 is 38340754908.
