Calculate the LCM of 677,418,215,780

Given numbers are 677,418,215,780

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

The LCM of 677,418,215,780 is 4745675220.

Find LCM of 677,418,215,780 with Prime Factorization


2 677, 418, 215, 780
5 677, 209, 215, 390
677, 209, 43, 78

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

2 x 5 x 677 x 209 x 43 x 78 = 4745675220

Therefore, the lowest common multiple of 677,418,215,780 is 4745675220.

LCM Formula to Find Lowest Common Multiple of 677,418,215,780

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.

677 x 418 x 215 x 780 = 47456752200

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.

677 : 1, 677

418 : 1, 2, 11, 19, 22, 38, 209, 418

215 : 1, 5, 43, 215

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 677,418,215,780, is 1.

Now, the common factors can be found like this.

677:677

418:2x 11x 19

215:5x 43

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 5 = 10

Therefore, the value for common factors is 10.

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 = 47456752200/(1x10)

LCM = 47456752200/10

LCM = 4745675220

Thus, we can understand that the LCM of 677,418,215,780 is 4745675220.
