Calculate the LCM of 255,698,780,957

Given numbers are 255,698,780,957

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

The LCM of 255,698,780,957 is 1476249060.

Find LCM of 255,698,780,957 with Prime Factorization


2 255, 698, 780, 957
3 255, 349, 390, 957
5 85, 349, 130, 319
17, 349, 26, 319

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

2 x 3 x 5 x 17 x 349 x 26 x 319 = 1476249060

Therefore, the lowest common multiple of 255,698,780,957 is 1476249060.

LCM Formula to Find Lowest Common Multiple of 255,698,780,957

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.

255 x 698 x 780 x 957 = 132862415400

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.

255 : 1, 3, 5, 15, 17, 51, 85, 255

698 : 1, 2, 349, 698

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

957 : 1, 3, 11, 29, 33, 87, 319, 957

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 255,698,780,957, is 1.

Now, the common factors can be found like this.

255:3x 5x 17

698:2x 349

780:2x 2x 3x 5x 13

957:3x 11x 29

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

2x 3x 3x 5 = 90

Therefore, the value for common factors is 90.

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 = 132862415400/(1x90)

LCM = 132862415400/90

LCM = 1476249060

Thus, we can understand that the LCM of 255,698,780,957 is 1476249060.
