Calculate the LCM of 904,905,961,794,765

Given numbers are 904,905,961,794,765

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

The LCM of 904,905,961,794,765 is 47755383270120.

Find LCM of 904,905,961,794,765 with Prime Factorization


2 904, 905, 961, 794, 765
5 452, 905, 961, 397, 765
452, 181, 961, 397, 153

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

2 x 5 x 452 x 181 x 961 x 397 x 153 = 47755383270120

Therefore, the lowest common multiple of 904,905,961,794,765 is 47755383270120.

LCM Formula to Find Lowest Common Multiple of 904,905,961,794,765

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.

904 x 905 x 961 x 794 x 765 = 477553832701200

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.

904 : 1, 2, 4, 8, 113, 226, 452, 904

905 : 1, 5, 181, 905

961 : 1, 31, 961

794 : 1, 2, 397, 794

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 904,905,961,794,765, is 1.

Now, the common factors can be found like this.

904:2x 2x 2x 113

905:5x 181

961:31x 31

794:2x 397

765:3x 3x 5x 17

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 477553832701200/(1x10)

LCM = 477553832701200/10

LCM = 47755383270120

Thus, we can understand that the LCM of 904,905,961,794,765 is 47755383270120.
