Calculate the LCM of 769,917,475,399

Given numbers are 769,917,475,399

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

The LCM of 769,917,475,399 is 1004871525.

Find LCM of 769,917,475,399 with Prime Factorization


7 769, 917, 475, 399
19 769, 131, 475, 57
769, 131, 25, 3

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

7 x 19 x 769 x 131 x 25 x 3 = 1004871525

Therefore, the lowest common multiple of 769,917,475,399 is 1004871525.

LCM Formula to Find Lowest Common Multiple of 769,917,475,399

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.

769 x 917 x 475 x 399 = 133647912825

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.

769 : 1, 769

917 : 1, 7, 131, 917

475 : 1, 5, 19, 25, 95, 475

399 : 1, 3, 7, 19, 21, 57, 133, 399

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 769,917,475,399, is 1.

Now, the common factors can be found like this.

769:769

917:7x 131

475:5x 5x 19

399:3x 7x 19

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

7x 19 = 133

Therefore, the value for common factors is 133.

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 = 133647912825/(1x133)

LCM = 133647912825/133

LCM = 1004871525

Thus, we can understand that the LCM of 769,917,475,399 is 1004871525.
