Calculate the LCM of 685,469,856,890

Given numbers are 685,469,856,890

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

The LCM of 685,469,856,890 is 24475252760.

Find LCM of 685,469,856,890 with Prime Factorization


2 685, 469, 856, 890
5 685, 469, 428, 445
137, 469, 428, 89

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

2 x 5 x 137 x 469 x 428 x 89 = 24475252760

Therefore, the lowest common multiple of 685,469,856,890 is 24475252760.

LCM Formula to Find Lowest Common Multiple of 685,469,856,890

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 469 x 856 x 890 = 244752527600

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

469 : 1, 7, 67, 469

856 : 1, 2, 4, 8, 107, 214, 428, 856

890 : 1, 2, 5, 10, 89, 178, 445, 890

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 685,469,856,890, is 1.

Now, the common factors can be found like this.

685:5x 137

469:7x 67

856:2x 2x 2x 107

890:2x 5x 89

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 244752527600/(1x10)

LCM = 244752527600/10

LCM = 24475252760

Thus, we can understand that the LCM of 685,469,856,890 is 24475252760.
