Calculate the LCM of 140,545,307,408

Given numbers are 140,545,307,408

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

The LCM of 140,545,307,408 is 477851640.

Find LCM of 140,545,307,408 with Prime Factorization


2 140, 545, 307, 408
2 70, 545, 307, 204
5 35, 545, 307, 102
7, 109, 307, 102

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

2 x 2 x 5 x 7 x 109 x 307 x 102 = 477851640

Therefore, the lowest common multiple of 140,545,307,408 is 477851640.

LCM Formula to Find Lowest Common Multiple of 140,545,307,408

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.

140 x 545 x 307 x 408 = 9557032800

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.

140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140

545 : 1, 5, 109, 545

307 : 1, 307

408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 140,545,307,408, is 1.

Now, the common factors can be found like this.

140:2x 2x 5x 7

545:5x 109

307:307

408:2x 2x 2x 3x 17

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 5 = 20

Therefore, the value for common factors is 20.

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 = 9557032800/(1x20)

LCM = 9557032800/20

LCM = 477851640

Thus, we can understand that the LCM of 140,545,307,408 is 477851640.
