Given numbers are 987,805,668,211,698

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

The LCM of 987,805,668,211,698 is 5583407656260.

Find LCM of 987,805,668,211,698 with Prime Factorization

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

2 x 7 x 141 x 115 x 334 x 211 x 349 = 5583407656260

Therefore, the lowest common multiple of 987,805,668,211,698 is 5583407656260.

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.

987 x 805 x 668 x 211 x 698 = 78167707187640

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.

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

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

668 : 1, 2, 4, 167, 334, 668

211 : 1, 211

698 : 1, 2, 349, 698

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 987,805,668,211,698, is 1.

Now, the common factors can be found like this.

987:3x 7x 47

805:5x 7x 23

668:2x 2x 167

211:211

698:2x 349

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

2x 7 = 14

Therefore, the value for common factors is 14.

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 = 78167707187640/(1x14)

LCM = 78167707187640/14

LCM = 5583407656260

Thus, we can understand that the LCM of 987,805,668,211,698 is 5583407656260.
