Calculate the LCM of 978,277,115,406,994

Given numbers are 978,277,115,406,994

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

The LCM of 978,277,115,406,994 is 449025340470.

Find LCM of 978,277,115,406,994 with Prime Factorization


2 978, 277, 115, 406, 994
7 489, 277, 115, 203, 497
489, 277, 115, 29, 71

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

2 x 7 x 489 x 277 x 115 x 29 x 71 = 449025340470

Therefore, the lowest common multiple of 978,277,115,406,994 is 449025340470.

LCM Formula to Find Lowest Common Multiple of 978,277,115,406,994

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.

978 x 277 x 115 x 406 x 994 = 12572709533160

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.

978 : 1, 2, 3, 6, 163, 326, 489, 978

277 : 1, 277

115 : 1, 5, 23, 115

406 : 1, 2, 7, 14, 29, 58, 203, 406

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 978,277,115,406,994, is 1.

Now, the common factors can be found like this.

978:2x 3x 163

277:277

115:5x 23

406:2x 7x 29

994:2x 7x 71

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

2x 2x 7 = 28

Therefore, the value for common factors is 28.

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 = 12572709533160/(1x28)

LCM = 12572709533160/28

LCM = 449025340470

Thus, we can understand that the LCM of 978,277,115,406,994 is 449025340470.
