Calculate the LCM of 994,989,972,218

Given numbers are 994,989,972,218

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

The LCM of 994,989,972,218 is 52076938284.

Find LCM of 994,989,972,218 with Prime Factorization


2 994, 989, 972, 218
497, 989, 486, 109

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

2 x 497 x 989 x 486 x 109 = 52076938284

Therefore, the lowest common multiple of 994,989,972,218 is 52076938284.

LCM Formula to Find Lowest Common Multiple of 994,989,972,218

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.

994 x 989 x 972 x 218 = 208307753136

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.

994 : 1, 2, 7, 14, 71, 142, 497, 994

989 : 1, 23, 43, 989

972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972

218 : 1, 2, 109, 218

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 994,989,972,218, is 1.

Now, the common factors can be found like this.

994:2x 7x 71

989:23x 43

972:2x 2x 3x 3x 3x 3x 3

218:2x 109

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 208307753136/(1x4)

LCM = 208307753136/4

LCM = 52076938284

Thus, we can understand that the LCM of 994,989,972,218 is 52076938284.
