Calculate the LCM of 678,791,160

Given numbers are 678,791,160

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

The LCM of 678,791,160 is 379680.

Find LCM of 678,791,160 with Prime Factorization


2 678, 791, 160
113 339, 791, 80
3, 7, 80

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

2 x 113 x 3 x 7 x 80 = 379680

Therefore, the lowest common multiple of 678,791,160 is 379680.

LCM Formula to Find Lowest Common Multiple of 678,791,160

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.

678 x 791 x 160 = 85807680

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.

678 : 1, 2, 3, 6, 113, 226, 339, 678

791 : 1, 7, 113, 791

160 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 678,791,160, is 1.

Now, the common factors can be found like this.

678:2x 3x 113

791:7x 113

160:2x 2x 2x 2x 2x 5

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

2x 113 = 226

Therefore, the value for common factors is 226.

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 = 85807680/(1x226)

LCM = 85807680/226

LCM = 379680

Thus, we can understand that the LCM of 678,791,160 is 379680.
