Given numbers are 688,933,622,421

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

The LCM of 688,933,622,421 is 270241584.

Find LCM of 688,933,622,421 with Prime Factorization

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

2 x 311 x 344 x 3 x 1 x 421 = 270241584

Therefore, the lowest common multiple of 688,933,622,421 is 270241584.

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.

688 x 933 x 622 x 421 = 168090265248

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.

688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688

933 : 1, 3, 311, 933

622 : 1, 2, 311, 622

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 688,933,622,421, is 1.

Now, the common factors can be found like this.

688:2x 2x 2x 2x 43

933:3x 311

622:2x 311

421:421

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

2x 311 = 622

Therefore, the value for common factors is 622.

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 = 168090265248/(1x622)

LCM = 168090265248/622

LCM = 270241584

Thus, we can understand that the LCM of 688,933,622,421 is 270241584.
