Calculate the LCM of 909,169,688,989

Given numbers are 909,169,688,989

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

The LCM of 909,169,688,989 is 2430898704.

Find LCM of 909,169,688,989 with Prime Factorization


43 909, 169, 688, 989
909, 169, 16, 23

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

43 x 909 x 169 x 16 x 23 = 2430898704

Therefore, the lowest common multiple of 909,169,688,989 is 2430898704.

LCM Formula to Find Lowest Common Multiple of 909,169,688,989

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.

909 x 169 x 688 x 989 = 104528644272

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.

909 : 1, 3, 9, 101, 303, 909

169 : 1, 13, 169

688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688

989 : 1, 23, 43, 989

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 909,169,688,989, is 1.

Now, the common factors can be found like this.

909:3x 3x 101

169:13x 13

688:2x 2x 2x 2x 43

989:23x 43

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

43 = 43

Therefore, the value for common factors is 43.

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 = 104528644272/(1x43)

LCM = 104528644272/43

LCM = 2430898704

Thus, we can understand that the LCM of 909,169,688,989 is 2430898704.
