Given numbers are 397,429,146,121

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

The LCM of 397,429,146,121 is 273522678.

Find LCM of 397,429,146,121 with Prime Factorization

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

11 x 397 x 39 x 146 x 11 = 273522678

Therefore, the lowest common multiple of 397,429,146,121 is 273522678.

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.

397 x 429 x 146 x 121 = 3008749458

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.

397 : 1, 397

429 : 1, 3, 11, 13, 33, 39, 143, 429

146 : 1, 2, 73, 146

121 : 1, 11, 121

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 397,429,146,121, is 1.

Now, the common factors can be found like this.

397:397

429:3x 11x 13

146:2x 73

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.

11 = 11

Therefore, the value for common factors is 11.

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 = 3008749458/(1x11)

LCM = 3008749458/11

LCM = 273522678

Thus, we can understand that the LCM of 397,429,146,121 is 273522678.
