Given numbers are 791,546,445,987

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

The LCM of 791,546,445,987 is 1290413670.

Find LCM of 791,546,445,987 with Prime Factorization

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

3 x 7 x 113 x 26 x 445 x 47 = 1290413670

Therefore, the lowest common multiple of 791,546,445,987 is 1290413670.

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.

791 x 546 x 445 x 987 = 189690809490

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.

791 : 1, 7, 113, 791

546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546

445 : 1, 5, 89, 445

987 : 1, 3, 7, 21, 47, 141, 329, 987

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 791,546,445,987, is 1.

Now, the common factors can be found like this.

791:7x 113

546:2x 3x 7x 13

445:5x 89

987:3x 7x 47

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

3x 7x 7 = 147

Therefore, the value for common factors is 147.

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 = 189690809490/(1x147)

LCM = 189690809490/147

LCM = 1290413670

Thus, we can understand that the LCM of 791,546,445,987 is 1290413670.
