Calculate the LCM of 144,657,691,142

Given numbers are 144,657,691,142

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

The LCM of 144,657,691,142 is 515729232.

Find LCM of 144,657,691,142 with Prime Factorization


2 144, 657, 691, 142
3 72, 657, 691, 71
3 24, 219, 691, 71
8, 73, 691, 71

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

2 x 3 x 3 x 8 x 73 x 691 x 71 = 515729232

Therefore, the lowest common multiple of 144,657,691,142 is 515729232.

LCM Formula to Find Lowest Common Multiple of 144,657,691,142

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.

144 x 657 x 691 x 142 = 9283126176

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.

144 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144

657 : 1, 3, 9, 73, 219, 657

691 : 1, 691

142 : 1, 2, 71, 142

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 144,657,691,142, is 1.

Now, the common factors can be found like this.

144:2x 2x 2x 2x 3x 3

657:3x 3x 73

691:691

142:2x 71

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 9283126176/(1x18)

LCM = 9283126176/18

LCM = 515729232

Thus, we can understand that the LCM of 144,657,691,142 is 515729232.
