Given numbers are 142,836,649,989

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

The LCM of 142,836,649,989 is 3463481956.

Find LCM of 142,836,649,989 with Prime Factorization

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

2 x 11 x 71 x 38 x 59 x 989 = 3463481956

Therefore, the lowest common multiple of 142,836,649,989 is 3463481956.

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.

142 x 836 x 649 x 989 = 76196603032

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.

142 : 1, 2, 71, 142

836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836

649 : 1, 11, 59, 649

989 : 1, 23, 43, 989

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 142,836,649,989, is 1.

Now, the common factors can be found like this.

142:2x 71

836:2x 2x 11x 19

649:11x 59

989:23x 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 11 = 22

Therefore, the value for common factors is 22.

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 = 76196603032/(1x22)

LCM = 76196603032/22

LCM = 3463481956

Thus, we can understand that the LCM of 142,836,649,989 is 3463481956.
