Given numbers are 691,488,793,945

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

The LCM of 691,488,793,945 is 4142600280.

Find LCM of 691,488,793,945 with Prime Factorization

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

61 x 691 x 8 x 13 x 945 = 4142600280

Therefore, the lowest common multiple of 691,488,793,945 is 4142600280.

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.

691 x 488 x 793 x 945 = 252698617080

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.

691 : 1, 691

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

793 : 1, 13, 61, 793

945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 691,488,793,945, is 1.

Now, the common factors can be found like this.

691:691

488:2x 2x 2x 61

793:13x 61

945:3x 3x 3x 5x 7

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

61 = 61

Therefore, the value for common factors is 61.

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 = 252698617080/(1x61)

LCM = 252698617080/61

LCM = 4142600280

Thus, we can understand that the LCM of 691,488,793,945 is 4142600280.
