Calculate the LCM of 847,216,377,638

Given numbers are 847,216,377,638

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

The LCM of 847,216,377,638 is 68972904.

Find LCM of 847,216,377,638 with Prime Factorization


2 847, 216, 377, 638
11 847, 108, 377, 319
29 77, 108, 377, 29
77, 108, 13, 1

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

2 x 11 x 29 x 77 x 108 x 13 x 1 = 68972904

Therefore, the lowest common multiple of 847,216,377,638 is 68972904.

LCM Formula to Find Lowest Common Multiple of 847,216,377,638

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.

847 x 216 x 377 x 638 = 44004712752

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.

847 : 1, 7, 11, 77, 121, 847

216 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 108, 216

377 : 1, 13, 29, 377

638 : 1, 2, 11, 22, 29, 58, 319, 638

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 847,216,377,638, is 1.

Now, the common factors can be found like this.

847:7x 11x 11

216:2x 2x 2x 3x 3x 3

377:13x 29

638:2x 11x 29

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

2x 11x 29 = 638

Therefore, the value for common factors is 638.

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 = 44004712752/(1x638)

LCM = 44004712752/638

LCM = 68972904

Thus, we can understand that the LCM of 847,216,377,638 is 68972904.
