Calculate the LCM of 605,438,626,370

Given numbers are 605,438,626,370

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

The LCM of 605,438,626,370 is 3068849190.

Find LCM of 605,438,626,370 with Prime Factorization


2 605, 438, 626, 370
5 605, 219, 313, 185
121, 219, 313, 37

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

2 x 5 x 121 x 219 x 313 x 37 = 3068849190

Therefore, the lowest common multiple of 605,438,626,370 is 3068849190.

LCM Formula to Find Lowest Common Multiple of 605,438,626,370

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.

605 x 438 x 626 x 370 = 61376983800

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.

605 : 1, 5, 11, 55, 121, 605

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

626 : 1, 2, 313, 626

370 : 1, 2, 5, 10, 37, 74, 185, 370

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 605,438,626,370, is 1.

Now, the common factors can be found like this.

605:5x 11x 11

438:2x 3x 73

626:2x 313

370:2x 5x 37

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

2x 2x 5 = 20

Therefore, the value for common factors is 20.

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 = 61376983800/(1x20)

LCM = 61376983800/20

LCM = 3068849190

Thus, we can understand that the LCM of 605,438,626,370 is 3068849190.
