Calculate the LCM of 387,598,782,655

Given numbers are 387,598,782,655

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

The LCM of 387,598,782,655 is 2576928510.

Find LCM of 387,598,782,655 with Prime Factorization


2 387, 598, 782, 655
23 387, 299, 391, 655
387, 13, 17, 655

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

2 x 23 x 387 x 13 x 17 x 655 = 2576928510

Therefore, the lowest common multiple of 387,598,782,655 is 2576928510.

LCM Formula to Find Lowest Common Multiple of 387,598,782,655

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.

387 x 598 x 782 x 655 = 118538711460

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.

387 : 1, 3, 9, 43, 129, 387

598 : 1, 2, 13, 23, 26, 46, 299, 598

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

655 : 1, 5, 131, 655

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 387,598,782,655, is 1.

Now, the common factors can be found like this.

387:3x 3x 43

598:2x 13x 23

782:2x 17x 23

655:5x 131

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

2x 23 = 46

Therefore, the value for common factors is 46.

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 = 118538711460/(1x46)

LCM = 118538711460/46

LCM = 2576928510

Thus, we can understand that the LCM of 387,598,782,655 is 2576928510.
