Calculate the LCM of 394,915,472,488

Given numbers are 394,915,472,488

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

The LCM of 394,915,472,488 is 85080360.

Find LCM of 394,915,472,488 with Prime Factorization


2 394, 915, 472, 488
2 197, 915, 236, 244
2 197, 915, 118, 122
61 197, 915, 59, 61
197, 15, 59, 1

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

2 x 2 x 2 x 61 x 197 x 15 x 59 x 1 = 85080360

Therefore, the lowest common multiple of 394,915,472,488 is 85080360.

LCM Formula to Find Lowest Common Multiple of 394,915,472,488

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.

394 x 915 x 472 x 488 = 83038431360

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.

394 : 1, 2, 197, 394

915 : 1, 3, 5, 15, 61, 183, 305, 915

472 : 1, 2, 4, 8, 59, 118, 236, 472

488 : 1, 2, 4, 8, 61, 122, 244, 488

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 394,915,472,488, is 1.

Now, the common factors can be found like this.

394:2x 197

915:3x 5x 61

472:2x 2x 2x 59

488:2x 2x 2x 61

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 2x 2x 61 = 976

Therefore, the value for common factors is 976.

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 = 83038431360/(1x976)

LCM = 83038431360/976

LCM = 85080360

Thus, we can understand that the LCM of 394,915,472,488 is 85080360.
