Calculate the LCM of 789,450,785,680

Given numbers are 789,450,785,680

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

The LCM of 789,450,785,680 is 1263504600.

Find LCM of 789,450,785,680 with Prime Factorization


2 789, 450, 785, 680
3 789, 225, 785, 340
5 263, 75, 785, 340
263, 15, 157, 68

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

2 x 3 x 5 x 263 x 15 x 157 x 68 = 1263504600

Therefore, the lowest common multiple of 789,450,785,680 is 1263504600.

LCM Formula to Find Lowest Common Multiple of 789,450,785,680

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 450 x 785 x 680 = 189525690000

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

450 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 75, 90, 150, 225, 450

785 : 1, 5, 157, 785

680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 789,450,785,680, is 1.

Now, the common factors can be found like this.

789:3x 263

450:2x 3x 3x 5x 5

785:5x 157

680:2x 2x 2x 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 3x 5x 5 = 150

Therefore, the value for common factors is 150.

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 = 189525690000/(1x150)

LCM = 189525690000/150

LCM = 1263504600

Thus, we can understand that the LCM of 789,450,785,680 is 1263504600.
