Calculate the LCM of 197,668,642,736

Given numbers are 197,668,642,736

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

The LCM of 197,668,642,736 is 7772586144.

Find LCM of 197,668,642,736 with Prime Factorization


2 197, 668, 642, 736
2 197, 334, 321, 368
197, 167, 321, 184

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

2 x 2 x 197 x 167 x 321 x 184 = 7772586144

Therefore, the lowest common multiple of 197,668,642,736 is 7772586144.

LCM Formula to Find Lowest Common Multiple of 197,668,642,736

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.

197 x 668 x 642 x 736 = 62180689152

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.

197 : 1, 197

668 : 1, 2, 4, 167, 334, 668

642 : 1, 2, 3, 6, 107, 214, 321, 642

736 : 1, 2, 4, 8, 16, 23, 32, 46, 92, 184, 368, 736

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 197,668,642,736, is 1.

Now, the common factors can be found like this.

197:197

668:2x 2x 167

642:2x 3x 107

736:2x 2x 2x 2x 2x 23

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 2 = 8

Therefore, the value for common factors is 8.

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 = 62180689152/(1x8)

LCM = 62180689152/8

LCM = 7772586144

Thus, we can understand that the LCM of 197,668,642,736 is 7772586144.
