Calculate the LCM of 685,243,493,978

Given numbers are 685,243,493,978

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

The LCM of 685,243,493,978 is 26752314690.

Find LCM of 685,243,493,978 with Prime Factorization


3 685, 243, 493, 978
685, 81, 493, 326

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

3 x 685 x 81 x 493 x 326 = 26752314690

Therefore, the lowest common multiple of 685,243,493,978 is 26752314690.

LCM Formula to Find Lowest Common Multiple of 685,243,493,978

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 243 x 493 x 978 = 80256944070

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

243 : 1, 3, 9, 27, 81, 243

493 : 1, 17, 29, 493

978 : 1, 2, 3, 6, 163, 326, 489, 978

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 685,243,493,978, is 1.

Now, the common factors can be found like this.

685:5x 137

243:3x 3x 3x 3x 3

493:17x 29

978:2x 3x 163

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

3 = 3

Therefore, the value for common factors is 3.

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 = 80256944070/(1x3)

LCM = 80256944070/3

LCM = 26752314690

Thus, we can understand that the LCM of 685,243,493,978 is 26752314690.
