Find LCM of 912,309,540,657 with Prime Factorization


2 912, 309, 540, 657
2 456, 309, 270, 657
3 228, 309, 135, 657
3 76, 103, 45, 219
76, 103, 15, 73

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

2 x 2 x 3 x 3 x 76 x 103 x 15 x 73 = 308579760

Therefore, the lowest common multiple of 912,309,540,657 is 308579760.

LCM Formula to Find Lowest Common Multiple of 912,309,540,657

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.

912 x 309 x 540 x 657 = 99979842240

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.

912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912

309 : 1, 3, 103, 309

540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540

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

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 912,309,540,657, is 3.

Now, the common factors can be found like this.

912:2x 2x 2x 2x 3x 19

309:3x 103

540:2x 2x 3x 3x 3x 5

657:3x 3x 73

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 3x 3 = 108

Therefore, the value for common factors is 108.

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 = 99979842240/(3x108)

LCM = 99979842240/324

LCM = 308579760

Thus, we can understand that the LCM of 912,309,540,657 is 308579760.
