Calculate the LCM of 640,270,309,467,901

Given numbers are 640,270,309,467,901

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

The LCM of 640,270,309,467,901 is 748897937280.

Find LCM of 640,270,309,467,901 with Prime Factorization


2 640, 270, 309, 467, 901
3 320, 135, 309, 467, 901
5 320, 45, 103, 467, 901
64, 9, 103, 467, 901

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

2 x 3 x 5 x 64 x 9 x 103 x 467 x 901 = 748897937280

Therefore, the lowest common multiple of 640,270,309,467,901 is 748897937280.

LCM Formula to Find Lowest Common Multiple of 640,270,309,467,901

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.

640 x 270 x 309 x 467 x 901 = 22466938118400

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.

640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640

270 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 90, 135, 270

309 : 1, 3, 103, 309

467 : 1, 467

901 : 1, 17, 53, 901

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 640,270,309,467,901, is 1.

Now, the common factors can be found like this.

640:2x 2x 2x 2x 2x 2x 2x 5

270:2x 3x 3x 3x 5

309:3x 103

467:467

901:17x 53

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 5 = 30

Therefore, the value for common factors is 30.

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 = 22466938118400/(1x30)

LCM = 22466938118400/30

LCM = 748897937280

Thus, we can understand that the LCM of 640,270,309,467,901 is 748897937280.
