Given numbers are 121,704,880,438,665

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

The LCM of 121,704,880,438,665 is 1127797440.

Find LCM of 121,704,880,438,665 with Prime Factorization

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

2 x 2 x 2 x 2 x 5 x 11 x 1 x 4 x 11 x 219 x 133 = 1127797440

Therefore, the lowest common multiple of 121,704,880,438,665 is 1127797440.

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.

121 x 704 x 880 x 438 x 665 = 21834158438400

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.

121 : 1, 11, 121

704 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 64, 88, 176, 352, 704

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

438 : 1, 2, 3, 6, 73, 146, 219, 438

665 : 1, 5, 7, 19, 35, 95, 133, 665

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,704,880,438,665, is 1.

Now, the common factors can be found like this.

121:11x 11

704:2x 2x 2x 2x 2x 2x 11

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

438:2x 3x 73

665:5x 7x 19

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 11x 11 = 19360

Therefore, the value for common factors is 19360.

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 = 21834158438400/(1x19360)

LCM = 21834158438400/19360

LCM = 1127797440

Thus, we can understand that the LCM of 121,704,880,438,665 is 1127797440.
