Given numbers are 681,272,370,745

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

The LCM of 681,272,370,745 is 5105920080.

Find LCM of 681,272,370,745 with Prime Factorization

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

2 x 5 x 681 x 136 x 37 x 149 = 5105920080

Therefore, the lowest common multiple of 681,272,370,745 is 5105920080.

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 272 x 370 x 745 = 51059200800

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

272 : 1, 2, 4, 8, 16, 17, 34, 68, 136, 272

370 : 1, 2, 5, 10, 37, 74, 185, 370

745 : 1, 5, 149, 745

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 681,272,370,745, is 1.

Now, the common factors can be found like this.

681:3x 227

272:2x 2x 2x 2x 17

370:2x 5x 37

745:5x 149

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 51059200800/(1x10)

LCM = 51059200800/10

LCM = 5105920080

Thus, we can understand that the LCM of 681,272,370,745 is 5105920080.

Here are some samples of LCM of two or more Numbers calculations.
