Given numbers are 617,438,377,689

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

The LCM of 617,438,377,689 is 5399785326.

Find LCM of 617,438,377,689 with Prime Factorization

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

13 x 617 x 438 x 29 x 53 = 5399785326

Therefore, the lowest common multiple of 617,438,377,689 is 5399785326.

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.

617 x 438 x 377 x 689 = 70197209238

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.

617 : 1, 617

438 : 1, 2, 3, 6, 73, 146, 219, 438

377 : 1, 13, 29, 377

689 : 1, 13, 53, 689

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 617,438,377,689, is 1.

Now, the common factors can be found like this.

617:617

438:2x 3x 73

377:13x 29

689:13x 53

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 = 70197209238/(1x13)

LCM = 70197209238/13

LCM = 5399785326

Thus, we can understand that the LCM of 617,438,377,689 is 5399785326.
