Calculate the LCM of 971,498,990,752,172

Given numbers are 971,498,990,752,172

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

The LCM of 971,498,990,752,172 is 1289997347760.

Find LCM of 971,498,990,752,172 with Prime Factorization


2 971, 498, 990, 752, 172
2 971, 249, 495, 376, 86
3 971, 249, 495, 188, 43
971, 83, 165, 188, 43

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

2 x 2 x 3 x 971 x 83 x 165 x 188 x 43 = 1289997347760

Therefore, the lowest common multiple of 971,498,990,752,172 is 1289997347760.

LCM Formula to Find Lowest Common Multiple of 971,498,990,752,172

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.

971 x 498 x 990 x 752 x 172 = 61919872692480

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.

971 : 1, 971

498 : 1, 2, 3, 6, 83, 166, 249, 498

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

752 : 1, 2, 4, 8, 16, 47, 94, 188, 376, 752

172 : 1, 2, 4, 43, 86, 172

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 971,498,990,752,172, is 1.

Now, the common factors can be found like this.

971:971

498:2x 3x 83

990:2x 3x 3x 5x 11

752:2x 2x 2x 2x 47

172:2x 2x 43

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 3 = 48

Therefore, the value for common factors is 48.

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 = 61919872692480/(1x48)

LCM = 61919872692480/48

LCM = 1289997347760

Thus, we can understand that the LCM of 971,498,990,752,172 is 1289997347760.
