Calculate the LCM of 924,891,851,749

Given numbers are 924,891,851,749

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

The LCM of 924,891,851,749 is 2271690036.

Find LCM of 924,891,851,749 with Prime Factorization


3 924, 891, 851, 749
7 308, 297, 851, 749
11 44, 297, 851, 107
4, 27, 851, 107

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

3 x 7 x 11 x 4 x 27 x 851 x 107 = 2271690036

Therefore, the lowest common multiple of 924,891,851,749 is 2271690036.

LCM Formula to Find Lowest Common Multiple of 924,891,851,749

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.

924 x 891 x 851 x 749 = 524760398316

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.

924 : 1, 2, 3, 4, 6, 7, 11, 12, 14, 21, 22, 28, 33, 42, 44, 66, 77, 84, 132, 154, 231, 308, 462, 924

891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891

851 : 1, 23, 37, 851

749 : 1, 7, 107, 749

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 924,891,851,749, is 1.

Now, the common factors can be found like this.

924:2x 2x 3x 7x 11

891:3x 3x 3x 3x 11

851:23x 37

749:7x 107

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

3x 7x 11 = 231

Therefore, the value for common factors is 231.

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 = 524760398316/(1x231)

LCM = 524760398316/231

LCM = 2271690036

Thus, we can understand that the LCM of 924,891,851,749 is 2271690036.
