Calculate the LCM of 523,965,381,780

Given numbers are 523,965,381,780

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

The LCM of 523,965,381,780 is 9999017340.

Find LCM of 523,965,381,780 with Prime Factorization


3 523, 965, 381, 780
5 523, 965, 127, 260
523, 193, 127, 52

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

3 x 5 x 523 x 193 x 127 x 52 = 9999017340

Therefore, the lowest common multiple of 523,965,381,780 is 9999017340.

LCM Formula to Find Lowest Common Multiple of 523,965,381,780

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.

523 x 965 x 381 x 780 = 149985260100

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.

523 : 1, 523

965 : 1, 5, 193, 965

381 : 1, 3, 127, 381

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 523,965,381,780, is 1.

Now, the common factors can be found like this.

523:523

965:5x 193

381:3x 127

780:2x 2x 3x 5x 13

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

3x 5 = 15

Therefore, the value for common factors is 15.

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 = 149985260100/(1x15)

LCM = 149985260100/15

LCM = 9999017340

Thus, we can understand that the LCM of 523,965,381,780 is 9999017340.
