The LCM of 169,747,921,931 is 36082395531.

Find LCM of 169,747,921,931 with Prime Factorization


3 169, 747, 921, 931
169, 249, 307, 931

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

3 x 169 x 249 x 307 x 931 = 36082395531

Therefore, the lowest common multiple of 169,747,921,931 is 36082395531.

LCM Formula to Find Lowest Common Multiple of 169,747,921,931

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.

169 x 747 x 921 x 931 = 108247186593

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.

169 : 1, 13, 169

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

921 : 1, 3, 307, 921

931 : 1, 7, 19, 49, 133, 931

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 169,747,921,931, is 1.

Now, the common factors can be found like this.

169:13x 13

747:3x 3x 83

921:3x 307

931:7x 7x 19

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

3 = 3

Therefore, the value for common factors is 3.

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 = 108247186593/(1x3)

LCM = 108247186593/3

LCM = 36082395531

Thus, we can understand that the LCM of 169,747,921,931 is 36082395531.
