Calculate the LCM of 782,214,611,540

Given numbers are 782,214,611,540

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

The LCM of 782,214,611,540 is 13803699780.

Find LCM of 782,214,611,540 with Prime Factorization


2 782, 214, 611, 540
391, 107, 611, 270

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

2 x 391 x 107 x 611 x 270 = 13803699780

Therefore, the lowest common multiple of 782,214,611,540 is 13803699780.

LCM Formula to Find Lowest Common Multiple of 782,214,611,540

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.

782 x 214 x 611 x 540 = 55214799120

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.

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

214 : 1, 2, 107, 214

611 : 1, 13, 47, 611

540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 782,214,611,540, is 1.

Now, the common factors can be found like this.

782:2x 17x 23

214:2x 107

611:13x 47

540:2x 2x 3x 3x 3x 5

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 55214799120/(1x4)

LCM = 55214799120/4

LCM = 13803699780

Thus, we can understand that the LCM of 782,214,611,540 is 13803699780.
