The LCM of 285,252,266,851 is 20372940.

Find LCM of 285,252,266,851 with Prime Factorization


2 285, 252, 266, 851
3 285, 126, 133, 851
7 95, 42, 133, 851
19 95, 6, 19, 851
5, 6, 1, 851

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

2 x 3 x 7 x 19 x 5 x 6 x 1 x 851 = 20372940

Therefore, the lowest common multiple of 285,252,266,851 is 20372940.

LCM Formula to Find Lowest Common Multiple of 285,252,266,851

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.

285 x 252 x 266 x 851 = 16257606120

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.

285 : 1, 3, 5, 15, 19, 57, 95, 285

252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252

266 : 1, 2, 7, 14, 19, 38, 133, 266

851 : 1, 23, 37, 851

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 285,252,266,851, is 1.

Now, the common factors can be found like this.

285:3x 5x 19

252:2x 2x 3x 3x 7

266:2x 7x 19

851:23x 37

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 7x 19 = 798

Therefore, the value for common factors is 798.

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 = 16257606120/(1x798)

LCM = 16257606120/798

LCM = 20372940

Thus, we can understand that the LCM of 285,252,266,851 is 20372940.
