Calculate the LCM of 680,101,661,388

Given numbers are 680,101,661,388

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

The LCM of 680,101,661,388 is 4403555560.

Find LCM of 680,101,661,388 with Prime Factorization


2 680, 101, 661, 388
2 340, 101, 661, 194
170, 101, 661, 97

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

2 x 2 x 170 x 101 x 661 x 97 = 4403555560

Therefore, the lowest common multiple of 680,101,661,388 is 4403555560.

LCM Formula to Find Lowest Common Multiple of 680,101,661,388

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.

680 x 101 x 661 x 388 = 17614222240

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.

680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680

101 : 1, 101

661 : 1, 661

388 : 1, 2, 4, 97, 194, 388

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 680,101,661,388, is 1.

Now, the common factors can be found like this.

680:2x 2x 2x 5x 17

101:101

661:661

388:2x 2x 97

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 = 17614222240/(1x4)

LCM = 17614222240/4

LCM = 4403555560

Thus, we can understand that the LCM of 680,101,661,388 is 4403555560.
