Calculate the LCM of 655,161,402,489

Given numbers are 655,161,402,489

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

The LCM of 655,161,402,489 is 6910044330.

Find LCM of 655,161,402,489 with Prime Factorization


3 655, 161, 402, 489
655, 161, 134, 163

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

3 x 655 x 161 x 134 x 163 = 6910044330

Therefore, the lowest common multiple of 655,161,402,489 is 6910044330.

LCM Formula to Find Lowest Common Multiple of 655,161,402,489

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.

655 x 161 x 402 x 489 = 20730132990

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.

655 : 1, 5, 131, 655

161 : 1, 7, 23, 161

402 : 1, 2, 3, 6, 67, 134, 201, 402

489 : 1, 3, 163, 489

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 655,161,402,489, is 1.

Now, the common factors can be found like this.

655:5x 131

161:7x 23

402:2x 3x 67

489:3x 163

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 = 20730132990/(1x3)

LCM = 20730132990/3

LCM = 6910044330

Thus, we can understand that the LCM of 655,161,402,489 is 6910044330.
