Calculate the LCM of 777,287,161,340

Given numbers are 777,287,161,340

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

The LCM of 777,287,161,340 is 249121740.

Find LCM of 777,287,161,340 with Prime Factorization


7 777, 287, 161, 340
111, 41, 23, 340

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

7 x 111 x 41 x 23 x 340 = 249121740

Therefore, the lowest common multiple of 777,287,161,340 is 249121740.

LCM Formula to Find Lowest Common Multiple of 777,287,161,340

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.

777 x 287 x 161 x 340 = 12206965260

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.

777 : 1, 3, 7, 21, 37, 111, 259, 777

287 : 1, 7, 41, 287

161 : 1, 7, 23, 161

340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 777,287,161,340, is 1.

Now, the common factors can be found like this.

777:3x 7x 37

287:7x 41

161:7x 23

340:2x 2x 5x 17

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

7x 7 = 49

Therefore, the value for common factors is 49.

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 = 12206965260/(1x49)

LCM = 12206965260/49

LCM = 249121740

Thus, we can understand that the LCM of 777,287,161,340 is 249121740.
