Calculate the LCM of 605,988,724,161

Given numbers are 605,988,724,161

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

The LCM of 605,988,724,161 is 17418741340.

Find LCM of 605,988,724,161 with Prime Factorization


2 605, 988, 724, 161
2 605, 494, 362, 161
605, 247, 181, 161

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

2 x 2 x 605 x 247 x 181 x 161 = 17418741340

Therefore, the lowest common multiple of 605,988,724,161 is 17418741340.

LCM Formula to Find Lowest Common Multiple of 605,988,724,161

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.

605 x 988 x 724 x 161 = 69674965360

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.

605 : 1, 5, 11, 55, 121, 605

988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988

724 : 1, 2, 4, 181, 362, 724

161 : 1, 7, 23, 161

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 605,988,724,161, is 1.

Now, the common factors can be found like this.

605:5x 11x 11

988:2x 2x 13x 19

724:2x 2x 181

161:7x 23

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 69674965360/(1x4)

LCM = 69674965360/4

LCM = 17418741340

Thus, we can understand that the LCM of 605,988,724,161 is 17418741340.
