Calculate the LCM of 987,940,408,766

Given numbers are 987,940,408,766

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

The LCM of 987,940,408,766 is 257054280.

Find LCM of 987,940,408,766 with Prime Factorization


2 987, 940, 408, 766
2 987, 470, 204, 383
3 987, 235, 102, 383
47 329, 235, 34, 383
7, 5, 34, 383

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

2 x 2 x 3 x 47 x 7 x 5 x 34 x 383 = 257054280

Therefore, the lowest common multiple of 987,940,408,766 is 257054280.

LCM Formula to Find Lowest Common Multiple of 987,940,408,766

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.

987 x 940 x 408 x 766 = 289957227840

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.

987 : 1, 3, 7, 21, 47, 141, 329, 987

940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940

408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408

766 : 1, 2, 383, 766

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 987,940,408,766, is 1.

Now, the common factors can be found like this.

987:3x 7x 47

940:2x 2x 5x 47

408:2x 2x 2x 3x 17

766:2x 383

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 3x 47 = 1128

Therefore, the value for common factors is 1128.

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 = 289957227840/(1x1128)

LCM = 289957227840/1128

LCM = 257054280

Thus, we can understand that the LCM of 987,940,408,766 is 257054280.
