Given numbers are 157,442,198,880

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

The LCM of 157,442,198,880 is 274800240.

Find LCM of 157,442,198,880 with Prime Factorization

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

2 x 11 x 157 x 221 x 9 x 40 = 274800240

Therefore, the lowest common multiple of 157,442,198,880 is 274800240.

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.

157 x 442 x 198 x 880 = 12091210560

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.

157 : 1, 157

442 : 1, 2, 13, 17, 26, 34, 221, 442

198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198

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 157,442,198,880, is 1.

Now, the common factors can be found like this.

157:157

442:2x 13x 17

198:2x 3x 3x 11

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 11 = 44

Therefore, the value for common factors is 44.

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 = 12091210560/(1x44)

LCM = 12091210560/44

LCM = 274800240

Thus, we can understand that the LCM of 157,442,198,880 is 274800240.
