Given numbers are 245,212,106,668,880

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

The LCM of 245,212,106,668,880 is 381655120.

Find LCM of 245,212,106,668,880 with Prime Factorization

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

2 x 2 x 5 x 53 x 49 x 1 x 1 x 167 x 44 = 381655120

Therefore, the lowest common multiple of 245,212,106,668,880 is 381655120.

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.

245 x 212 x 106 x 668 x 880 = 3236435417600

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.

245 : 1, 5, 7, 35, 49, 245

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

106 : 1, 2, 53, 106

668 : 1, 2, 4, 167, 334, 668

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 245,212,106,668,880, is 1.

Now, the common factors can be found like this.

245:5x 7x 7

212:2x 2x 53

106:2x 53

668:2x 2x 167

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 2x 2x 5x 53 = 8480

Therefore, the value for common factors is 8480.

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 = 3236435417600/(1x8480)

LCM = 3236435417600/8480

LCM = 381655120

Thus, we can understand that the LCM of 245,212,106,668,880 is 381655120.
