The LCM of 611,728,423,917 is 40340664.

Find LCM of 611,728,423,917 with Prime Factorization


7 611, 728, 423, 917
13 611, 104, 423, 131
47 47, 8, 423, 131
1, 8, 9, 131

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

7 x 13 x 47 x 1 x 8 x 9 x 131 = 40340664

Therefore, the lowest common multiple of 611,728,423,917 is 40340664.

LCM Formula to Find Lowest Common Multiple of 611,728,423,917

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.

611 x 728 x 423 x 917 = 172537019928

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.

611 : 1, 13, 47, 611

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

423 : 1, 3, 9, 47, 141, 423

917 : 1, 7, 131, 917

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 611,728,423,917, is 1.

Now, the common factors can be found like this.

611:13x 47

728:2x 2x 2x 7x 13

423:3x 3x 47

917:7x 131

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

7x 13x 47 = 4277

Therefore, the value for common factors is 4277.

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 = 172537019928/(1x4277)

LCM = 172537019928/4277

LCM = 40340664

Thus, we can understand that the LCM of 611,728,423,917 is 40340664.
