Calculate the LCM of 484,707,891,505

Given numbers are 484,707,891,505

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

The LCM of 484,707,891,505 is 138586140.

Find LCM of 484,707,891,505 with Prime Factorization


11 484, 707, 891, 505
101 44, 707, 81, 505
44, 7, 81, 5

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

11 x 101 x 44 x 7 x 81 x 5 = 138586140

Therefore, the lowest common multiple of 484,707,891,505 is 138586140.

LCM Formula to Find Lowest Common Multiple of 484,707,891,505

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.

484 x 707 x 891 x 505 = 153969201540

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.

484 : 1, 2, 4, 11, 22, 44, 121, 242, 484

707 : 1, 7, 101, 707

891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891

505 : 1, 5, 101, 505

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 484,707,891,505, is 1.

Now, the common factors can be found like this.

484:2x 2x 11x 11

707:7x 101

891:3x 3x 3x 3x 11

505:5x 101

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

11x 101 = 1111

Therefore, the value for common factors is 1111.

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 = 153969201540/(1x1111)

LCM = 153969201540/1111

LCM = 138586140

Thus, we can understand that the LCM of 484,707,891,505 is 138586140.
