Calculate the LCM of 787,240,525,817

Given numbers are 787,240,525,817

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

The LCM of 787,240,525,817 is 5401023600.

Find LCM of 787,240,525,817 with Prime Factorization


3 787, 240, 525, 817
5 787, 80, 175, 817
787, 16, 35, 817

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

3 x 5 x 787 x 16 x 35 x 817 = 5401023600

Therefore, the lowest common multiple of 787,240,525,817 is 5401023600.

LCM Formula to Find Lowest Common Multiple of 787,240,525,817

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.

787 x 240 x 525 x 817 = 81015354000

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.

787 : 1, 787

240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240

525 : 1, 3, 5, 7, 15, 21, 25, 35, 75, 105, 175, 525

817 : 1, 19, 43, 817

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 787,240,525,817, is 1.

Now, the common factors can be found like this.

787:787

240:2x 2x 2x 2x 3x 5

525:3x 5x 5x 7

817:19x 43

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

3x 5 = 15

Therefore, the value for common factors is 15.

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 = 81015354000/(1x15)

LCM = 81015354000/15

LCM = 5401023600

Thus, we can understand that the LCM of 787,240,525,817 is 5401023600.
