Given numbers are 421,830,199,554

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

The LCM of 421,830,199,554 is 19261629890.

Find LCM of 421,830,199,554 with Prime Factorization

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

2 x 421 x 415 x 199 x 277 = 19261629890

Therefore, the lowest common multiple of 421,830,199,554 is 19261629890.

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 830 x 199 x 554 = 38523259780

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

830 : 1, 2, 5, 10, 83, 166, 415, 830

199 : 1, 199

554 : 1, 2, 277, 554

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,830,199,554, is 1.

Now, the common factors can be found like this.

421:421

830:2x 5x 83

199:199

554:2x 277

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 = 38523259780/(1x2)

LCM = 38523259780/2

LCM = 19261629890

Thus, we can understand that the LCM of 421,830,199,554 is 19261629890.
