Calculate the LCM of 785,453,400

Given numbers are 785,453,400

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

The LCM of 785,453,400 is 28448400.

Find LCM of 785,453,400 with Prime Factorization


5 785, 453, 400
157, 453, 80

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

5 x 157 x 453 x 80 = 28448400

Therefore, the lowest common multiple of 785,453,400 is 28448400.

LCM Formula to Find Lowest Common Multiple of 785,453,400

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.

785 x 453 x 400 = 142242000

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.

785 : 1, 5, 157, 785

453 : 1, 3, 151, 453

400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 785,453,400, is 1.

Now, the common factors can be found like this.

785:5x 157

453:3x 151

400:2x 2x 2x 2x 5x 5

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

5 = 5

Therefore, the value for common factors is 5.

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 = 142242000/(1x5)

LCM = 142242000/5

LCM = 28448400

Thus, we can understand that the LCM of 785,453,400 is 28448400.
