Calculate the LCM of 401,660,492,780

Given numbers are 401,660,492,780

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

The LCM of 401,660,492,780 is 141063780.

Find LCM of 401,660,492,780 with Prime Factorization


2 401, 660, 492, 780
2 401, 330, 246, 390
3 401, 165, 123, 195
5 401, 55, 41, 65
401, 11, 41, 13

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

2 x 2 x 3 x 5 x 401 x 11 x 41 x 13 = 141063780

Therefore, the lowest common multiple of 401,660,492,780 is 141063780.

LCM Formula to Find Lowest Common Multiple of 401,660,492,780

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.

401 x 660 x 492 x 780 = 101565921600

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.

401 : 1, 401

660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660

492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492

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 401,660,492,780, is 1.

Now, the common factors can be found like this.

401:401

660:2x 2x 3x 5x 11

492:2x 2x 3x 41

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.

2x 2x 2x 2x 3x 3x 5 = 720

Therefore, the value for common factors is 720.

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 = 101565921600/(1x720)

LCM = 101565921600/720

LCM = 141063780

Thus, we can understand that the LCM of 401,660,492,780 is 141063780.
