Given numbers are 660,203,970,880

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

The LCM of 660,203,970,880 is 51984240.

Find LCM of 660,203,970,880 with Prime Factorization

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

2 x 2 x 5 x 11 x 3 x 203 x 97 x 4 = 51984240

Therefore, the lowest common multiple of 660,203,970,880 is 51984240.

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.

660 x 203 x 970 x 880 = 114365328000

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.

660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660

203 : 1, 7, 29, 203

970 : 1, 2, 5, 10, 97, 194, 485, 970

880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 660,203,970,880, is 1.

Now, the common factors can be found like this.

660:2x 2x 3x 5x 11

203:7x 29

970:2x 5x 97

880:2x 2x 2x 2x 5x 11

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

2x 2x 2x 5x 5x 11 = 2200

Therefore, the value for common factors is 2200.

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 = 114365328000/(1x2200)

LCM = 114365328000/2200

LCM = 51984240

Thus, we can understand that the LCM of 660,203,970,880 is 51984240.
