Calculate the LCM of 640,732,190,933

Given numbers are 640,732,190,933

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

The LCM of 640,732,190,933 is 692062080.

Find LCM of 640,732,190,933 with Prime Factorization


2 640, 732, 190, 933
2 320, 366, 95, 933
3 160, 183, 95, 933
5 160, 61, 95, 311
32, 61, 19, 311

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

2 x 2 x 3 x 5 x 32 x 61 x 19 x 311 = 692062080

Therefore, the lowest common multiple of 640,732,190,933 is 692062080.

LCM Formula to Find Lowest Common Multiple of 640,732,190,933

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 732 x 190 x 933 = 83047449600

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

732 : 1, 2, 3, 4, 6, 12, 61, 122, 183, 244, 366, 732

190 : 1, 2, 5, 10, 19, 38, 95, 190

933 : 1, 3, 311, 933

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 640,732,190,933, is 1.

Now, the common factors can be found like this.

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

732:2x 2x 3x 61

190:2x 5x 19

933:3x 311

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 2x 3x 5 = 120

Therefore, the value for common factors is 120.

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 = 83047449600/(1x120)

LCM = 83047449600/120

LCM = 692062080

Thus, we can understand that the LCM of 640,732,190,933 is 692062080.
