Calculate the LCM of 787,221,403,936

Given numbers are 787,221,403,936

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

The LCM of 787,221,403,936 is 388205064.

Find LCM of 787,221,403,936 with Prime Factorization


13 787, 221, 403, 936
787, 17, 31, 72

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

13 x 787 x 17 x 31 x 72 = 388205064

Therefore, the lowest common multiple of 787,221,403,936 is 388205064.

LCM Formula to Find Lowest Common Multiple of 787,221,403,936

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 221 x 403 x 936 = 65606655816

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

221 : 1, 13, 17, 221

403 : 1, 13, 31, 403

936 : 1, 2, 3, 4, 6, 8, 9, 12, 13, 18, 24, 26, 36, 39, 52, 72, 78, 104, 117, 156, 234, 312, 468, 936

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 787,221,403,936, is 1.

Now, the common factors can be found like this.

787:787

221:13x 17

403:13x 31

936:2x 2x 2x 3x 3x 13

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

13x 13 = 169

Therefore, the value for common factors is 169.

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 = 65606655816/(1x169)

LCM = 65606655816/169

LCM = 388205064

Thus, we can understand that the LCM of 787,221,403,936 is 388205064.
