Given numbers are 397,172,677,940

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

The LCM of 397,172,677,940 is 10863642980.

Find LCM of 397,172,677,940 with Prime Factorization

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

2 x 2 x 397 x 43 x 677 x 235 = 10863642980

Therefore, the lowest common multiple of 397,172,677,940 is 10863642980.

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 172 x 677 x 940 = 43454571920

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

172 : 1, 2, 4, 43, 86, 172

677 : 1, 677

940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 397,172,677,940, is 1.

Now, the common factors can be found like this.

397:397

172:2x 2x 43

677:677

940:2x 2x 5x 47

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 = 43454571920/(1x4)

LCM = 43454571920/4

LCM = 10863642980

Thus, we can understand that the LCM of 397,172,677,940 is 10863642980.
