Calculate the LCM of 485,690,407,880

Given numbers are 485,690,407,880

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

The LCM of 485,690,407,880 is 217924080.

Find LCM of 485,690,407,880 with Prime Factorization


2 485, 690, 407, 880
5 485, 345, 407, 440
11 97, 69, 407, 88
97, 69, 37, 8

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

2 x 5 x 11 x 97 x 69 x 37 x 8 = 217924080

Therefore, the lowest common multiple of 485,690,407,880 is 217924080.

LCM Formula to Find Lowest Common Multiple of 485,690,407,880

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.

485 x 690 x 407 x 880 = 119858244000

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.

485 : 1, 5, 97, 485

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

407 : 1, 11, 37, 407

880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 485,690,407,880, is 1.

Now, the common factors can be found like this.

485:5x 97

690:2x 3x 5x 23

407:11x 37

880:2x 2x 2x 2x 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.

2x 5x 5x 11 = 550

Therefore, the value for common factors is 550.

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 = 119858244000/(1x550)

LCM = 119858244000/550

LCM = 217924080

Thus, we can understand that the LCM of 485,690,407,880 is 217924080.
