Calculate the LCM of 728,398,377,314,227

Given numbers are 728,398,377,314,227

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

The LCM of 728,398,377,314,227 is 149729703032.

Find LCM of 728,398,377,314,227 with Prime Factorization


2 728, 398, 377, 314, 227
13 364, 199, 377, 157, 227
28, 199, 29, 157, 227

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

2 x 13 x 28 x 199 x 29 x 157 x 227 = 149729703032

Therefore, the lowest common multiple of 728,398,377,314,227 is 149729703032.

LCM Formula to Find Lowest Common Multiple of 728,398,377,314,227

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.

728 x 398 x 377 x 314 x 227 = 7785944557664

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.

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

398 : 1, 2, 199, 398

377 : 1, 13, 29, 377

314 : 1, 2, 157, 314

227 : 1, 227

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 728,398,377,314,227, is 1.

Now, the common factors can be found like this.

728:2x 2x 2x 7x 13

398:2x 199

377:13x 29

314:2x 157

227:227

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 13 = 52

Therefore, the value for common factors is 52.

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 = 7785944557664/(1x52)

LCM = 7785944557664/52

LCM = 149729703032

Thus, we can understand that the LCM of 728,398,377,314,227 is 149729703032.
