Calculate the LCM of 789,123,574,310

Given numbers are 789,123,574,310

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

The LCM of 789,123,574,310 is 70197330.

Find LCM of 789,123,574,310 with Prime Factorization


2 789, 123, 574, 310
3 789, 123, 287, 155
41 263, 41, 287, 155
263, 1, 7, 155

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

2 x 3 x 41 x 263 x 1 x 7 x 155 = 70197330

Therefore, the lowest common multiple of 789,123,574,310 is 70197330.

LCM Formula to Find Lowest Common Multiple of 789,123,574,310

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 123 x 574 x 310 = 17268543180

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

123 : 1, 3, 41, 123

574 : 1, 2, 7, 14, 41, 82, 287, 574

310 : 1, 2, 5, 10, 31, 62, 155, 310

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 789,123,574,310, is 1.

Now, the common factors can be found like this.

789:3x 263

123:3x 41

574:2x 7x 41

310:2x 5x 31

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

2x 3x 41 = 246

Therefore, the value for common factors is 246.

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 = 17268543180/(1x246)

LCM = 17268543180/246

LCM = 70197330

Thus, we can understand that the LCM of 789,123,574,310 is 70197330.
