Given numbers are 991,305,507,427

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

The LCM of 991,305,507,427 is 1072702995.

Find LCM of 991,305,507,427 with Prime Factorization

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

61 x 991 x 5 x 507 x 7 = 1072702995

Therefore, the lowest common multiple of 991,305,507,427 is 1072702995.

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.

991 x 305 x 507 x 427 = 65434882695

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.

991 : 1, 991

305 : 1, 5, 61, 305

507 : 1, 3, 13, 39, 169, 507

427 : 1, 7, 61, 427

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,305,507,427, is 1.

Now, the common factors can be found like this.

991:991

305:5x 61

507:3x 13x 13

427:7x 61

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 = 65434882695/(1x61)

LCM = 65434882695/61

LCM = 1072702995

Thus, we can understand that the LCM of 991,305,507,427 is 1072702995.
