Calculate the LCM of 791,489,183,216,438

Given numbers are 791,489,183,216,438

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

The LCM of 791,489,183,216,438 is 124013948184.

Find LCM of 791,489,183,216,438 with Prime Factorization


2 791, 489, 183, 216, 438
3 791, 489, 183, 108, 219
791, 163, 61, 36, 73

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

2 x 3 x 791 x 163 x 61 x 36 x 73 = 124013948184

Therefore, the lowest common multiple of 791,489,183,216,438 is 124013948184.

LCM Formula to Find Lowest Common Multiple of 791,489,183,216,438

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.

791 x 489 x 183 x 216 x 438 = 6696753201936

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.

791 : 1, 7, 113, 791

489 : 1, 3, 163, 489

183 : 1, 3, 61, 183

216 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 108, 216

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 791,489,183,216,438, is 1.

Now, the common factors can be found like this.

791:7x 113

489:3x 163

183:3x 61

216:2x 2x 2x 3x 3x 3

438:2x 3x 73

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

2x 3x 3x 3 = 54

Therefore, the value for common factors is 54.

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 = 6696753201936/(1x54)

LCM = 6696753201936/54

LCM = 124013948184

Thus, we can understand that the LCM of 791,489,183,216,438 is 124013948184.
