Given numbers are 289,840,661,523,791

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

The LCM of 289,840,661,523,791 is 9483283211640.

Find LCM of 289,840,661,523,791 with Prime Factorization

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

7 x 289 x 120 x 661 x 523 x 113 = 9483283211640

Therefore, the lowest common multiple of 289,840,661,523,791 is 9483283211640.

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.

289 x 840 x 661 x 523 x 791 = 66382982481480

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.

289 : 1, 17, 289

840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840

661 : 1, 661

523 : 1, 523

791 : 1, 7, 113, 791

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 289,840,661,523,791, is 1.

Now, the common factors can be found like this.

289:17x 17

840:2x 2x 2x 3x 5x 7

661:661

523:523

791:7x 113

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

7 = 7

Therefore, the value for common factors is 7.

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 = 66382982481480/(1x7)

LCM = 66382982481480/7

LCM = 9483283211640

Thus, we can understand that the LCM of 289,840,661,523,791 is 9483283211640.
