Calculate the LCM of 988,636,766,143

Given numbers are 988,636,766,143

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

The LCM of 988,636,766,143 is 661828596.

Find LCM of 988,636,766,143 with Prime Factorization


2 988, 636, 766, 143
2 494, 318, 383, 143
13 247, 159, 383, 143
19, 159, 383, 11

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

2 x 2 x 13 x 19 x 159 x 383 x 11 = 661828596

Therefore, the lowest common multiple of 988,636,766,143 is 661828596.

LCM Formula to Find Lowest Common Multiple of 988,636,766,143

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.

988 x 636 x 766 x 143 = 68830173984

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.

988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988

636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636

766 : 1, 2, 383, 766

143 : 1, 11, 13, 143

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 988,636,766,143, is 1.

Now, the common factors can be found like this.

988:2x 2x 13x 19

636:2x 2x 3x 53

766:2x 383

143:11x 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 13 = 104

Therefore, the value for common factors is 104.

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 = 68830173984/(1x104)

LCM = 68830173984/104

LCM = 661828596

Thus, we can understand that the LCM of 988,636,766,143 is 661828596.
