Given numbers are 212,775,740,640

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

The LCM of 212,775,740,640 is 194531200.

Find LCM of 212,775,740,640 with Prime Factorization

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

2 x 2 x 5 x 53 x 155 x 37 x 32 = 194531200

Therefore, the lowest common multiple of 212,775,740,640 is 194531200.

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.

212 x 775 x 740 x 640 = 77812480000

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.

212 : 1, 2, 4, 53, 106, 212

775 : 1, 5, 25, 31, 155, 775

740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740

640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 212,775,740,640, is 1.

Now, the common factors can be found like this.

212:2x 2x 53

775:5x 5x 31

740:2x 2x 5x 37

640:2x 2x 2x 2x 2x 2x 2x 5

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 2x 5x 5 = 400

Therefore, the value for common factors is 400.

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 = 77812480000/(1x400)

LCM = 77812480000/400

LCM = 194531200

Thus, we can understand that the LCM of 212,775,740,640 is 194531200.
