Calculate the LCM of 642,884,183,868

Given numbers are 642,884,183,868

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

The LCM of 642,884,183,868 is 3756184068.

Find LCM of 642,884,183,868 with Prime Factorization


2 642, 884, 183, 868
2 321, 442, 183, 434
3 321, 221, 183, 217
107, 221, 61, 217

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

2 x 2 x 3 x 107 x 221 x 61 x 217 = 3756184068

Therefore, the lowest common multiple of 642,884,183,868 is 3756184068.

LCM Formula to Find Lowest Common Multiple of 642,884,183,868

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 884 x 183 x 868 = 90148417632

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

884 : 1, 2, 4, 13, 17, 26, 34, 52, 68, 221, 442, 884

183 : 1, 3, 61, 183

868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,884,183,868, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

884:2x 2x 13x 17

183:3x 61

868:2x 2x 7x 31

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 2x 3 = 24

Therefore, the value for common factors is 24.

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 = 90148417632/(1x24)

LCM = 90148417632/24

LCM = 3756184068

Thus, we can understand that the LCM of 642,884,183,868 is 3756184068.
