Calculate the LCM of 850,554,221,989

Given numbers are 850,554,221,989

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

The LCM of 850,554,221,989 is 3027180650.

Find LCM of 850,554,221,989 with Prime Factorization


2 850, 554, 221, 989
17 425, 277, 221, 989
25, 277, 13, 989

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

2 x 17 x 25 x 277 x 13 x 989 = 3027180650

Therefore, the lowest common multiple of 850,554,221,989 is 3027180650.

LCM Formula to Find Lowest Common Multiple of 850,554,221,989

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.

850 x 554 x 221 x 989 = 102924142100

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.

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

554 : 1, 2, 277, 554

221 : 1, 13, 17, 221

989 : 1, 23, 43, 989

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 850,554,221,989, is 1.

Now, the common factors can be found like this.

850:2x 5x 5x 17

554:2x 277

221:13x 17

989:23x 43

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

2x 17 = 34

Therefore, the value for common factors is 34.

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 = 102924142100/(1x34)

LCM = 102924142100/34

LCM = 3027180650

Thus, we can understand that the LCM of 850,554,221,989 is 3027180650.
