Given numbers are 554,661,214,421

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

The LCM of 554,661,214,421 is 16495941118.

Find LCM of 554,661,214,421 with Prime Factorization

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

2 x 277 x 661 x 107 x 421 = 16495941118

Therefore, the lowest common multiple of 554,661,214,421 is 16495941118.

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.

554 x 661 x 214 x 421 = 32991882236

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.

554 : 1, 2, 277, 554

661 : 1, 661

214 : 1, 2, 107, 214

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 554,661,214,421, is 1.

Now, the common factors can be found like this.

554:2x 277

661:661

214:2x 107

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.

2 = 2

Therefore, the value for common factors is 2.

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 = 32991882236/(1x2)

LCM = 32991882236/2

LCM = 16495941118

Thus, we can understand that the LCM of 554,661,214,421 is 16495941118.
