Calculate the LCM of 789,905,707,912

Given numbers are 789,905,707,912

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

The LCM of 789,905,707,912 is 153468263760.

Find LCM of 789,905,707,912 with Prime Factorization


3 789, 905, 707, 912
263, 905, 707, 304

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

3 x 263 x 905 x 707 x 304 = 153468263760

Therefore, the lowest common multiple of 789,905,707,912 is 153468263760.

LCM Formula to Find Lowest Common Multiple of 789,905,707,912

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.

789 x 905 x 707 x 912 = 460404791280

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.

789 : 1, 3, 263, 789

905 : 1, 5, 181, 905

707 : 1, 7, 101, 707

912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 789,905,707,912, is 1.

Now, the common factors can be found like this.

789:3x 263

905:5x 181

707:7x 101

912:2x 2x 2x 2x 3x 19

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

3 = 3

Therefore, the value for common factors is 3.

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 = 460404791280/(1x3)

LCM = 460404791280/3

LCM = 153468263760

Thus, we can understand that the LCM of 789,905,707,912 is 153468263760.
