Given numbers are 617,805,437,987

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

The LCM of 617,805,437,987 is 1330619115.

Find LCM of 617,805,437,987 with Prime Factorization

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

7 x 23 x 617 x 5 x 19 x 141 = 1330619115

Therefore, the lowest common multiple of 617,805,437,987 is 1330619115.

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.

617 x 805 x 437 x 987 = 214229677515

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.

617 : 1, 617

805 : 1, 5, 7, 23, 35, 115, 161, 805

437 : 1, 19, 23, 437

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 617,805,437,987, is 1.

Now, the common factors can be found like this.

617:617

805:5x 7x 23

437:19x 23

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.

7x 23 = 161

Therefore, the value for common factors is 161.

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 = 214229677515/(1x161)

LCM = 214229677515/161

LCM = 1330619115

Thus, we can understand that the LCM of 617,805,437,987 is 1330619115.
