Calculate the LCM of 678,302,440,555

Given numbers are 678,302,440,555

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

The LCM of 678,302,440,555 is 833356920.

Find LCM of 678,302,440,555 with Prime Factorization


2 678, 302, 440, 555
3 339, 151, 220, 555
5 113, 151, 220, 185
113, 151, 44, 37

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

2 x 3 x 5 x 113 x 151 x 44 x 37 = 833356920

Therefore, the lowest common multiple of 678,302,440,555 is 833356920.

LCM Formula to Find Lowest Common Multiple of 678,302,440,555

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.

678 x 302 x 440 x 555 = 50001415200

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.

678 : 1, 2, 3, 6, 113, 226, 339, 678

302 : 1, 2, 151, 302

440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440

555 : 1, 3, 5, 15, 37, 111, 185, 555

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 678,302,440,555, is 1.

Now, the common factors can be found like this.

678:2x 3x 113

302:2x 151

440:2x 2x 2x 5x 11

555:3x 5x 37

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 5 = 60

Therefore, the value for common factors is 60.

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 = 50001415200/(1x60)

LCM = 50001415200/60

LCM = 833356920

Thus, we can understand that the LCM of 678,302,440,555 is 833356920.
