Calculate the LCM of 684,161,649,153

Given numbers are 684,161,649,153

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

The LCM of 684,161,649,153 is 1214998092.

Find LCM of 684,161,649,153 with Prime Factorization


3 684, 161, 649, 153
3 228, 161, 649, 51
76, 161, 649, 17

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

3 x 3 x 76 x 161 x 649 x 17 = 1214998092

Therefore, the lowest common multiple of 684,161,649,153 is 1214998092.

LCM Formula to Find Lowest Common Multiple of 684,161,649,153

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.

684 x 161 x 649 x 153 = 10934982828

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.

684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684

161 : 1, 7, 23, 161

649 : 1, 11, 59, 649

153 : 1, 3, 9, 17, 51, 153

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 684,161,649,153, is 1.

Now, the common factors can be found like this.

684:2x 2x 3x 3x 19

161:7x 23

649:11x 59

153:3x 3x 17

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

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 10934982828/(1x9)

LCM = 10934982828/9

LCM = 1214998092

Thus, we can understand that the LCM of 684,161,649,153 is 1214998092.
