Given numbers are 221,869,611,791

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

The LCM of 221,869,611,791 is 7139805673.

Find LCM of 221,869,611,791 with Prime Factorization

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

13 x 17 x 869 x 47 x 791 = 7139805673

Therefore, the lowest common multiple of 221,869,611,791 is 7139805673.

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.

221 x 869 x 611 x 791 = 92817473749

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.

221 : 1, 13, 17, 221

869 : 1, 11, 79, 869

611 : 1, 13, 47, 611

791 : 1, 7, 113, 791

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,869,611,791, is 1.

Now, the common factors can be found like this.

221:13x 17

869:11x 79

611:13x 47

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.

13 = 13

Therefore, the value for common factors is 13.

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 = 92817473749/(1x13)

LCM = 92817473749/13

LCM = 7139805673

Thus, we can understand that the LCM of 221,869,611,791 is 7139805673.
