Calculate the LCM of 699,812,978,885

Given numbers are 699,812,978,885

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

The LCM of 699,812,978,885 is 27292468980.

Find LCM of 699,812,978,885 with Prime Factorization


2 699, 812, 978, 885
3 699, 406, 489, 885
233, 406, 163, 295

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

2 x 3 x 233 x 406 x 163 x 295 = 27292468980

Therefore, the lowest common multiple of 699,812,978,885 is 27292468980.

LCM Formula to Find Lowest Common Multiple of 699,812,978,885

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.

699 x 812 x 978 x 885 = 491264441640

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.

699 : 1, 3, 233, 699

812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812

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

885 : 1, 3, 5, 15, 59, 177, 295, 885

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 699,812,978,885, is 1.

Now, the common factors can be found like this.

699:3x 233

812:2x 2x 7x 29

978:2x 3x 163

885:3x 5x 59

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

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 491264441640/(1x18)

LCM = 491264441640/18

LCM = 27292468980

Thus, we can understand that the LCM of 699,812,978,885 is 27292468980.
