Given numbers are 421,242,809,790

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

The LCM of 421,242,809,790 is 32556902510.

Find LCM of 421,242,809,790 with Prime Factorization

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

2 x 421 x 121 x 809 x 395 = 32556902510

Therefore, the lowest common multiple of 421,242,809,790 is 32556902510.

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 242 x 809 x 790 = 65113805020

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

242 : 1, 2, 11, 22, 121, 242

809 : 1, 809

790 : 1, 2, 5, 10, 79, 158, 395, 790

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,242,809,790, is 1.

Now, the common factors can be found like this.

421:421

242:2x 11x 11

809:809

790:2x 5x 79

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 = 65113805020/(1x2)

LCM = 65113805020/2

LCM = 32556902510

Thus, we can understand that the LCM of 421,242,809,790 is 32556902510.
