The LCM of 144,676,299,645 is 120341520.

Find LCM of 144,676,299,645 with Prime Factorization


2 144, 676, 299, 645
2 72, 338, 299, 645
3 36, 169, 299, 645
13 12, 169, 299, 215
12, 13, 23, 215

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

2 x 2 x 3 x 13 x 12 x 13 x 23 x 215 = 120341520

Therefore, the lowest common multiple of 144,676,299,645 is 120341520.

LCM Formula to Find Lowest Common Multiple of 144,676,299,645

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 676 x 299 x 645 = 18773277120

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

676 : 1, 2, 4, 13, 26, 52, 169, 338, 676

299 : 1, 13, 23, 299

645 : 1, 3, 5, 15, 43, 129, 215, 645

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 144,676,299,645, is 1.

Now, the common factors can be found like this.

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

676:2x 2x 13x 13

299:13x 23

645:3x 5x 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 3x 13 = 156

Therefore, the value for common factors is 156.

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 = 18773277120/(1x156)

LCM = 18773277120/156

LCM = 120341520

Thus, we can understand that the LCM of 144,676,299,645 is 120341520.
