Calculate the LCM of 831,707,545,445,680

Given numbers are 831,707,545,445,680

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

The LCM of 831,707,545,445,680 is 3875661643560.

Find LCM of 831,707,545,445,680 with Prime Factorization


5 831, 707, 545, 445, 680
831, 707, 109, 89, 136

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

5 x 831 x 707 x 109 x 89 x 136 = 3875661643560

Therefore, the lowest common multiple of 831,707,545,445,680 is 3875661643560.

LCM Formula to Find Lowest Common Multiple of 831,707,545,445,680

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.

831 x 707 x 545 x 445 x 680 = 96891541089000

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.

831 : 1, 3, 277, 831

707 : 1, 7, 101, 707

545 : 1, 5, 109, 545

445 : 1, 5, 89, 445

680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 831,707,545,445,680, is 1.

Now, the common factors can be found like this.

831:3x 277

707:7x 101

545:5x 109

445:5x 89

680:2x 2x 2x 5x 17

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

5x 5 = 25

Therefore, the value for common factors is 25.

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 = 96891541089000/(1x25)

LCM = 96891541089000/25

LCM = 3875661643560

Thus, we can understand that the LCM of 831,707,545,445,680 is 3875661643560.
