Calculate the LCM of 397,320,445,757

Given numbers are 397,320,445,757

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

The LCM of 397,320,445,757 is 8559065920.

Find LCM of 397,320,445,757 with Prime Factorization


5 397, 320, 445, 757
397, 64, 89, 757

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

5 x 397 x 64 x 89 x 757 = 8559065920

Therefore, the lowest common multiple of 397,320,445,757 is 8559065920.

LCM Formula to Find Lowest Common Multiple of 397,320,445,757

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.

397 x 320 x 445 x 757 = 42795329600

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.

397 : 1, 397

320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320

445 : 1, 5, 89, 445

757 : 1, 757

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 397,320,445,757, is 1.

Now, the common factors can be found like this.

397:397

320:2x 2x 2x 2x 2x 2x 5

445:5x 89

757:757

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

5 = 5

Therefore, the value for common factors is 5.

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 = 42795329600/(1x5)

LCM = 42795329600/5

LCM = 8559065920

Thus, we can understand that the LCM of 397,320,445,757 is 8559065920.
