The LCM of 957,521,987,165 is 820192065.

Find LCM of 957,521,987,165 with Prime Factorization


3 957, 521, 987, 165
11 319, 521, 329, 55
29, 521, 329, 5

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

3 x 11 x 29 x 521 x 329 x 5 = 820192065

Therefore, the lowest common multiple of 957,521,987,165 is 820192065.

LCM Formula to Find Lowest Common Multiple of 957,521,987,165

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.

957 x 521 x 987 x 165 = 81199014435

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.

957 : 1, 3, 11, 29, 33, 87, 319, 957

521 : 1, 521

987 : 1, 3, 7, 21, 47, 141, 329, 987

165 : 1, 3, 5, 11, 15, 33, 55, 165

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 957,521,987,165, is 1.

Now, the common factors can be found like this.

957:3x 11x 29

521:521

987:3x 7x 47

165:3x 5x 11

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

3x 3x 11 = 99

Therefore, the value for common factors is 99.

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 = 81199014435/(1x99)

LCM = 81199014435/99

LCM = 820192065

Thus, we can understand that the LCM of 957,521,987,165 is 820192065.
