Given numbers are 769,988,117,991

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

The LCM of 769,988,117,991 is 6776406468.

Find LCM of 769,988,117,991 with Prime Factorization

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

13 x 769 x 76 x 9 x 991 = 6776406468

Therefore, the lowest common multiple of 769,988,117,991 is 6776406468.

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.

769 x 988 x 117 x 991 = 88093284084

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.

769 : 1, 769

988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988

117 : 1, 3, 9, 13, 39, 117

991 : 1, 991

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 769,988,117,991, is 1.

Now, the common factors can be found like this.

769:769

988:2x 2x 13x 19

117:3x 3x 13

991:991

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 = 88093284084/(1x13)

LCM = 88093284084/13

LCM = 6776406468

Thus, we can understand that the LCM of 769,988,117,991 is 6776406468.
