Given numbers are 520,253,274,121

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

The LCM of 520,253,274,121 is 198260920.

Find LCM of 520,253,274,121 with Prime Factorization

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

2 x 11 x 260 x 23 x 137 x 11 = 198260920

Therefore, the lowest common multiple of 520,253,274,121 is 198260920.

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.

520 x 253 x 274 x 121 = 4361740240

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.

520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520

253 : 1, 11, 23, 253

274 : 1, 2, 137, 274

121 : 1, 11, 121

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 520,253,274,121, is 1.

Now, the common factors can be found like this.

520:2x 2x 2x 5x 13

253:11x 23

274:2x 137

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.

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 4361740240/(1x22)

LCM = 4361740240/22

LCM = 198260920

Thus, we can understand that the LCM of 520,253,274,121 is 198260920.
