Calculate the LCM of 916,174,783,620

Given numbers are 916,174,783,620

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

The LCM of 916,174,783,620 is 111170340.

Find LCM of 916,174,783,620 with Prime Factorization


2 916, 174, 783, 620
2 458, 87, 783, 310
3 229, 87, 783, 155
29 229, 29, 261, 155
229, 1, 9, 155

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

2 x 2 x 3 x 29 x 229 x 1 x 9 x 155 = 111170340

Therefore, the lowest common multiple of 916,174,783,620 is 111170340.

LCM Formula to Find Lowest Common Multiple of 916,174,783,620

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.

916 x 174 x 783 x 620 = 77374556640

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.

916 : 1, 2, 4, 229, 458, 916

174 : 1, 2, 3, 6, 29, 58, 87, 174

783 : 1, 3, 9, 27, 29, 87, 261, 783

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 916,174,783,620, is 1.

Now, the common factors can be found like this.

916:2x 2x 229

174:2x 3x 29

783:3x 3x 3x 29

620:2x 2x 5x 31

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

2x 2x 2x 3x 29 = 696

Therefore, the value for common factors is 696.

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 = 77374556640/(1x696)

LCM = 77374556640/696

LCM = 111170340

Thus, we can understand that the LCM of 916,174,783,620 is 111170340.
