Given numbers are 531,122,391,122

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

The LCM of 531,122,391,122 is 25329762.

Find LCM of 531,122,391,122 with Prime Factorization

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

2 x 61 x 531 x 1 x 391 x 1 = 25329762

Therefore, the lowest common multiple of 531,122,391,122 is 25329762.

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.

531 x 122 x 391 x 122 = 3090230964

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.

531 : 1, 3, 9, 59, 177, 531

122 : 1, 2, 61, 122

391 : 1, 17, 23, 391

122 : 1, 2, 61, 122

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 531,122,391,122, is 1.

Now, the common factors can be found like this.

531:3x 3x 59

122:2x 61

391:17x 23

122:2x 61

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

2x 61 = 122

Therefore, the value for common factors is 122.

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 = 3090230964/(1x122)

LCM = 3090230964/122

LCM = 25329762

Thus, we can understand that the LCM of 531,122,391,122 is 25329762.
