Find LCM of 636,154,644,828 with Prime Factorization


2 636, 154, 644, 828
2 318, 77, 322, 414
3 159, 77, 161, 207
7 53, 77, 161, 69
23 53, 11, 23, 69
53, 11, 1, 3

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

2 x 2 x 3 x 7 x 23 x 53 x 11 x 1 x 3 = 3379068

Therefore, the lowest common multiple of 636,154,644,828 is 3379068.

LCM Formula to Find Lowest Common Multiple of 636,154,644,828

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.

636 x 154 x 644 x 828 = 52226875008

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.

636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636

154 : 1, 2, 7, 11, 14, 22, 77, 154

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 636,154,644,828, is 2.

Now, the common factors can be found like this.

636:2x 2x 3x 53

154:2x 7x 11

644:2x 2x 7x 23

828:2x 2x 3x 3x 23

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 2x 2x 3x 7x 23 = 7728

Therefore, the value for common factors is 7728.

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 = 52226875008/(2x7728)

LCM = 52226875008/15456

LCM = 3379068

Thus, we can understand that the LCM of 636,154,644,828 is 3379068.
