Calculate the LCM of 754,689,144,129

Given numbers are 754,689,144,129

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

The LCM of 754,689,144,129 is 123722352.

Find LCM of 754,689,144,129 with Prime Factorization


2 754, 689, 144, 129
3 377, 689, 72, 129
13 377, 689, 24, 43
29, 53, 24, 43

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

2 x 3 x 13 x 29 x 53 x 24 x 43 = 123722352

Therefore, the lowest common multiple of 754,689,144,129 is 123722352.

LCM Formula to Find Lowest Common Multiple of 754,689,144,129

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.

754 x 689 x 144 x 129 = 9650343456

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.

754 : 1, 2, 13, 26, 29, 58, 377, 754

689 : 1, 13, 53, 689

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

129 : 1, 3, 43, 129

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 754,689,144,129, is 1.

Now, the common factors can be found like this.

754:2x 13x 29

689:13x 53

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

129:3x 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 3x 13 = 78

Therefore, the value for common factors is 78.

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 = 9650343456/(1x78)

LCM = 9650343456/78

LCM = 123722352

Thus, we can understand that the LCM of 754,689,144,129 is 123722352.
