Given numbers are 967,989,638,161

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

The LCM of 967,989,638,161 is 4271117158.

Find LCM of 967,989,638,161 with Prime Factorization

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

23 x 967 x 43 x 638 x 7 = 4271117158

Therefore, the lowest common multiple of 967,989,638,161 is 4271117158.

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.

967 x 989 x 638 x 161 = 98235694634

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.

967 : 1, 967

989 : 1, 23, 43, 989

638 : 1, 2, 11, 22, 29, 58, 319, 638

161 : 1, 7, 23, 161

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 967,989,638,161, is 1.

Now, the common factors can be found like this.

967:967

989:23x 43

638:2x 11x 29

161:7x 23

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

23 = 23

Therefore, the value for common factors is 23.

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 = 98235694634/(1x23)

LCM = 98235694634/23

LCM = 4271117158

Thus, we can understand that the LCM of 967,989,638,161 is 4271117158.
