Calculate the LCM of 689,551,465,611

Given numbers are 689,551,465,611

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

The LCM of 689,551,465,611 is 8297010345.

Find LCM of 689,551,465,611 with Prime Factorization


13 689, 551, 465, 611
53, 551, 465, 47

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

13 x 53 x 551 x 465 x 47 = 8297010345

Therefore, the lowest common multiple of 689,551,465,611 is 8297010345.

LCM Formula to Find Lowest Common Multiple of 689,551,465,611

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.

689 x 551 x 465 x 611 = 107861134485

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.

689 : 1, 13, 53, 689

551 : 1, 19, 29, 551

465 : 1, 3, 5, 15, 31, 93, 155, 465

611 : 1, 13, 47, 611

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,551,465,611, is 1.

Now, the common factors can be found like this.

689:13x 53

551:19x 29

465:3x 5x 31

611:13x 47

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

13 = 13

Therefore, the value for common factors is 13.

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 = 107861134485/(1x13)

LCM = 107861134485/13

LCM = 8297010345

Thus, we can understand that the LCM of 689,551,465,611 is 8297010345.
