Given numbers are 421,122,274,732

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

The LCM of 421,122,274,732 is 42219564.

Find LCM of 421,122,274,732 with Prime Factorization

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

2 x 61 x 421 x 1 x 137 x 6 = 42219564

Therefore, the lowest common multiple of 421,122,274,732 is 42219564.

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.

421 x 122 x 274 x 732 = 10301573616

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.

421 : 1, 421

122 : 1, 2, 61, 122

274 : 1, 2, 137, 274

732 : 1, 2, 3, 4, 6, 12, 61, 122, 183, 244, 366, 732

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,122,274,732, is 1.

Now, the common factors can be found like this.

421:421

122:2x 61

274:2x 137

732:2x 2x 3x 61

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 61 = 244

Therefore, the value for common factors is 244.

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 = 10301573616/(1x244)

LCM = 10301573616/244

LCM = 42219564

Thus, we can understand that the LCM of 421,122,274,732 is 42219564.
