Calculate the LCM of 642,367,910,565

Given numbers are 642,367,910,565

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

The LCM of 642,367,910,565 is 12114093810.

Find LCM of 642,367,910,565 with Prime Factorization


2 642, 367, 910, 565
5 321, 367, 455, 565
321, 367, 91, 113

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

2 x 5 x 321 x 367 x 91 x 113 = 12114093810

Therefore, the lowest common multiple of 642,367,910,565 is 12114093810.

LCM Formula to Find Lowest Common Multiple of 642,367,910,565

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.

642 x 367 x 910 x 565 = 121140938100

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.

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

367 : 1, 367

910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910

565 : 1, 5, 113, 565

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,367,910,565, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

367:367

910:2x 5x 7x 13

565:5x 113

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 121140938100/(1x10)

LCM = 121140938100/10

LCM = 12114093810

Thus, we can understand that the LCM of 642,367,910,565 is 12114093810.
