Given numbers are 628,128,812,569,644

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

The LCM of 628,128,812,569,644 is 53388259456.

Find LCM of 628,128,812,569,644 with Prime Factorization

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

2 x 2 x 7 x 157 x 32 x 29 x 569 x 23 = 53388259456

Therefore, the lowest common multiple of 628,128,812,569,644 is 53388259456.

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.

628 x 128 x 812 x 569 x 644 = 23917940236288

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.

628 : 1, 2, 4, 157, 314, 628

128 : 1, 2, 4, 8, 16, 32, 64, 128

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

569 : 1, 569

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 628,128,812,569,644, is 1.

Now, the common factors can be found like this.

628:2x 2x 157

128:2x 2x 2x 2x 2x 2x 2

812:2x 2x 7x 29

569:569

644:2x 2x 7x 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 2x 2x 7 = 448

Therefore, the value for common factors is 448.

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 = 23917940236288/(1x448)

LCM = 23917940236288/448

LCM = 53388259456

Thus, we can understand that the LCM of 628,128,812,569,644 is 53388259456.
