Calculate the LCM of 397,521,546,750

Given numbers are 397,521,546,750

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

The LCM of 397,521,546,750 is 14116625250.

Find LCM of 397,521,546,750 with Prime Factorization


2 397, 521, 546, 750
3 397, 521, 273, 375
397, 521, 91, 125

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

2 x 3 x 397 x 521 x 91 x 125 = 14116625250

Therefore, the lowest common multiple of 397,521,546,750 is 14116625250.

LCM Formula to Find Lowest Common Multiple of 397,521,546,750

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 521 x 546 x 750 = 84699751500

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

521 : 1, 521

546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546

750 : 1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75, 125, 150, 250, 375, 750

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 397,521,546,750, is 1.

Now, the common factors can be found like this.

397:397

521:521

546:2x 3x 7x 13

750:2x 3x 5x 5x 5

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 84699751500/(1x6)

LCM = 84699751500/6

LCM = 14116625250

Thus, we can understand that the LCM of 397,521,546,750 is 14116625250.
