Calculate the LCM of 185,747,921,504,438

Given numbers are 185,747,921,504,438

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

The LCM of 185,747,921,504,438 is 173436936120.

Find LCM of 185,747,921,504,438 with Prime Factorization


2 185, 747, 921, 504, 438
3 185, 747, 921, 252, 219
3 185, 249, 307, 84, 73
185, 83, 307, 28, 73

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

2 x 3 x 3 x 185 x 83 x 307 x 28 x 73 = 173436936120

Therefore, the lowest common multiple of 185,747,921,504,438 is 173436936120.

LCM Formula to Find Lowest Common Multiple of 185,747,921,504,438

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.

185 x 747 x 921 x 504 x 438 = 28096783651440

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.

185 : 1, 5, 37, 185

747 : 1, 3, 9, 83, 249, 747

921 : 1, 3, 307, 921

504 : 1, 2, 3, 4, 6, 7, 8, 9, 12, 14, 18, 21, 24, 28, 36, 42, 56, 63, 72, 84, 126, 168, 252, 504

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 185,747,921,504,438, is 1.

Now, the common factors can be found like this.

185:5x 37

747:3x 3x 83

921:3x 307

504:2x 2x 2x 3x 3x 7

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 3x 3 = 162

Therefore, the value for common factors is 162.

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 = 28096783651440/(1x162)

LCM = 28096783651440/162

LCM = 173436936120

Thus, we can understand that the LCM of 185,747,921,504,438 is 173436936120.
