Calculate the LCM of 945,709,789,831,145

Given numbers are 945,709,789,831,145

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

The LCM of 945,709,789,831,145 is 1415505493395.

Find LCM of 945,709,789,831,145 with Prime Factorization


3 945, 709, 789, 831, 145
5 315, 709, 263, 277, 145
63, 709, 263, 277, 29

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

3 x 5 x 63 x 709 x 263 x 277 x 29 = 1415505493395

Therefore, the lowest common multiple of 945,709,789,831,145 is 1415505493395.

LCM Formula to Find Lowest Common Multiple of 945,709,789,831,145

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.

945 x 709 x 789 x 831 x 145 = 63697747202775

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.

945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945

709 : 1, 709

789 : 1, 3, 263, 789

831 : 1, 3, 277, 831

145 : 1, 5, 29, 145

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 945,709,789,831,145, is 1.

Now, the common factors can be found like this.

945:3x 3x 3x 5x 7

709:709

789:3x 263

831:3x 277

145:5x 29

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

3x 3x 5 = 45

Therefore, the value for common factors is 45.

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 = 63697747202775/(1x45)

LCM = 63697747202775/45

LCM = 1415505493395

Thus, we can understand that the LCM of 945,709,789,831,145 is 1415505493395.
