Calculate the LCM of 605,968,642

Given numbers are 605,968,642

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

The LCM of 605,968,642 is 1553640.

Find LCM of 605,968,642 with Prime Factorization


2 605, 968, 642
11 605, 484, 321
11 55, 44, 321
5, 4, 321

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

2 x 11 x 11 x 5 x 4 x 321 = 1553640

Therefore, the lowest common multiple of 605,968,642 is 1553640.

LCM Formula to Find Lowest Common Multiple of 605,968,642

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 968 x 642 = 375980880

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

968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968

642 : 1, 2, 3, 6, 107, 214, 321, 642

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 605,968,642, is 1.

Now, the common factors can be found like this.

605:5x 11x 11

968:2x 2x 2x 11x 11

642:2x 3x 107

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

2x 11x 11 = 242

Therefore, the value for common factors is 242.

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 = 375980880/(1x242)

LCM = 375980880/242

LCM = 1553640

Thus, we can understand that the LCM of 605,968,642 is 1553640.
