Calculate the LCM of 987,200,850,955

Given numbers are 987,200,850,955

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

The LCM of 987,200,850,955 is 640957800.

Find LCM of 987,200,850,955 with Prime Factorization


2 987, 200, 850, 955
5 987, 100, 425, 955
5 987, 20, 85, 191
987, 4, 17, 191

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

2 x 5 x 5 x 987 x 4 x 17 x 191 = 640957800

Therefore, the lowest common multiple of 987,200,850,955 is 640957800.

LCM Formula to Find Lowest Common Multiple of 987,200,850,955

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 200 x 850 x 955 = 160239450000

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

200 : 1, 2, 4, 5, 8, 10, 20, 25, 40, 50, 100, 200

850 : 1, 2, 5, 10, 17, 25, 34, 50, 85, 170, 425, 850

955 : 1, 5, 191, 955

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 987,200,850,955, is 1.

Now, the common factors can be found like this.

987:3x 7x 47

200:2x 2x 2x 5x 5

850:2x 5x 5x 17

955:5x 191

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

2x 5x 5x 5 = 250

Therefore, the value for common factors is 250.

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 = 160239450000/(1x250)

LCM = 160239450000/250

LCM = 640957800

Thus, we can understand that the LCM of 987,200,850,955 is 640957800.
