The LCM of 804,782,391,770 is 121030140.

Find LCM of 804,782,391,770 with Prime Factorization


2 804, 782, 391, 770
17 402, 391, 391, 385
23 402, 23, 23, 385
402, 1, 1, 385

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

2 x 17 x 23 x 402 x 1 x 1 x 385 = 121030140

Therefore, the lowest common multiple of 804,782,391,770 is 121030140.

LCM Formula to Find Lowest Common Multiple of 804,782,391,770

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.

804 x 782 x 391 x 770 = 189291138960

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.

804 : 1, 2, 3, 4, 6, 12, 67, 134, 201, 268, 402, 804

782 : 1, 2, 17, 23, 34, 46, 391, 782

391 : 1, 17, 23, 391

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 804,782,391,770, is 1.

Now, the common factors can be found like this.

804:2x 2x 3x 67

782:2x 17x 23

391:17x 23

770:2x 5x 7x 11

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 17x 23 = 1564

Therefore, the value for common factors is 1564.

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 = 189291138960/(1x1564)

LCM = 189291138960/1564

LCM = 121030140

Thus, we can understand that the LCM of 804,782,391,770 is 121030140.
