Calculate the LCM of 685,814,520,976

Given numbers are 685,814,520,976

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

The LCM of 685,814,520,976 is 3537350960.

Find LCM of 685,814,520,976 with Prime Factorization


2 685, 814, 520, 976
2 685, 407, 260, 488
2 685, 407, 130, 244
5 685, 407, 65, 122
137, 407, 13, 122

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

2 x 2 x 2 x 5 x 137 x 407 x 13 x 122 = 3537350960

Therefore, the lowest common multiple of 685,814,520,976 is 3537350960.

LCM Formula to Find Lowest Common Multiple of 685,814,520,976

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.

685 x 814 x 520 x 976 = 282988076800

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.

685 : 1, 5, 137, 685

814 : 1, 2, 11, 22, 37, 74, 407, 814

520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520

976 : 1, 2, 4, 8, 16, 61, 122, 244, 488, 976

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 685,814,520,976, is 1.

Now, the common factors can be found like this.

685:5x 137

814:2x 11x 37

520:2x 2x 2x 5x 13

976:2x 2x 2x 2x 61

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

2x 2x 2x 2x 5 = 80

Therefore, the value for common factors is 80.

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 = 282988076800/(1x80)

LCM = 282988076800/80

LCM = 3537350960

Thus, we can understand that the LCM of 685,814,520,976 is 3537350960.
