Calculate the LCM of 21,318,635

Given numbers are 21,318,635

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

The LCM of 21,318,635 is 1413510.

Find LCM of 21,318,635 with Prime Factorization


3 21, 318, 635
7, 106, 635

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

3 x 7 x 106 x 635 = 1413510

Therefore, the lowest common multiple of 21,318,635 is 1413510.

LCM Formula to Find Lowest Common Multiple of 21,318,635

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.

21 x 318 x 635 = 4240530

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.

21 : 1, 3, 7, 21

318 : 1, 2, 3, 6, 53, 106, 159, 318

635 : 1, 5, 127, 635

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 21,318,635, is 1.

Now, the common factors can be found like this.

21:3x 7

318:2x 3x 53

635:5x 127

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

3 = 3

Therefore, the value for common factors is 3.

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 = 4240530/(1x3)

LCM = 4240530/3

LCM = 1413510

Thus, we can understand that the LCM of 21,318,635 is 1413510.
