Calculate the LCM of 118,645,505,765,121

Given numbers are 118,645,505,765,121

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

The LCM of 118,645,505,765,121 is 47437155810.

Find LCM of 118,645,505,765,121 with Prime Factorization


3 118, 645, 505, 765, 121
5 118, 215, 505, 255, 121
118, 43, 101, 51, 121

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

3 x 5 x 118 x 43 x 101 x 51 x 121 = 47437155810

Therefore, the lowest common multiple of 118,645,505,765,121 is 47437155810.

LCM Formula to Find Lowest Common Multiple of 118,645,505,765,121

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.

118 x 645 x 505 x 765 x 121 = 3557786685750

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.

118 : 1, 2, 59, 118

645 : 1, 3, 5, 15, 43, 129, 215, 645

505 : 1, 5, 101, 505

765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765

121 : 1, 11, 121

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 118,645,505,765,121, is 1.

Now, the common factors can be found like this.

118:2x 59

645:3x 5x 43

505:5x 101

765:3x 3x 5x 17

121:11x 11

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

3x 5x 5 = 75

Therefore, the value for common factors is 75.

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 = 3557786685750/(1x75)

LCM = 3557786685750/75

LCM = 47437155810

Thus, we can understand that the LCM of 118,645,505,765,121 is 47437155810.
