Given numbers are 421,290,421,121

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

The LCM of 421,290,421,121 is 14772890.

Find LCM of 421,290,421,121 with Prime Factorization

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

421 x 1 x 290 x 1 x 121 = 14772890

Therefore, the lowest common multiple of 421,290,421,121 is 14772890.

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 290 x 421 x 121 = 6219386690

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

290 : 1, 2, 5, 10, 29, 58, 145, 290

421 : 1, 421

121 : 1, 11, 121

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,290,421,121, is 1.

Now, the common factors can be found like this.

421:421

290:2x 5x 29

421:421

121:11x 11

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

421 = 421

Therefore, the value for common factors is 421.

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 = 6219386690/(1x421)

LCM = 6219386690/421

LCM = 14772890

Thus, we can understand that the LCM of 421,290,421,121 is 14772890.
