Calculate the LCM of 157,847,770,918

Given numbers are 157,847,770,918

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

The LCM of 157,847,770,918 is 610373610.

Find LCM of 157,847,770,918 with Prime Factorization


2 157, 847, 770, 918
7 157, 847, 385, 459
11 157, 121, 55, 459
157, 11, 5, 459

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

2 x 7 x 11 x 157 x 11 x 5 x 459 = 610373610

Therefore, the lowest common multiple of 157,847,770,918 is 610373610.

LCM Formula to Find Lowest Common Multiple of 157,847,770,918

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.

157 x 847 x 770 x 918 = 93997535940

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.

157 : 1, 157

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

770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770

918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 157,847,770,918, is 1.

Now, the common factors can be found like this.

157:157

847:7x 11x 11

770:2x 5x 7x 11

918:2x 3x 3x 3x 17

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

2x 7x 11 = 154

Therefore, the value for common factors is 154.

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 = 93997535940/(1x154)

LCM = 93997535940/154

LCM = 610373610

Thus, we can understand that the LCM of 157,847,770,918 is 610373610.
