Calculate the LCM of 805,685,775,697

Given numbers are 805,685,775,697

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

The LCM of 805,685,775,697 is 11914639975.

Find LCM of 805,685,775,697 with Prime Factorization


5 805, 685, 775, 697
161, 137, 155, 697

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

5 x 161 x 137 x 155 x 697 = 11914639975

Therefore, the lowest common multiple of 805,685,775,697 is 11914639975.

LCM Formula to Find Lowest Common Multiple of 805,685,775,697

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.

805 x 685 x 775 x 697 = 297865999375

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.

805 : 1, 5, 7, 23, 35, 115, 161, 805

685 : 1, 5, 137, 685

775 : 1, 5, 25, 31, 155, 775

697 : 1, 17, 41, 697

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 805,685,775,697, is 1.

Now, the common factors can be found like this.

805:5x 7x 23

685:5x 137

775:5x 5x 31

697:17x 41

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

5x 5 = 25

Therefore, the value for common factors is 25.

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 = 297865999375/(1x25)

LCM = 297865999375/25

LCM = 11914639975

Thus, we can understand that the LCM of 805,685,775,697 is 11914639975.
