Find LCM of 272,656,451,978 with Prime Factorization


2 272, 656, 451, 978
2 136, 328, 451, 489
2 68, 164, 451, 489
2 34, 82, 451, 489
41 17, 41, 451, 489
17, 1, 11, 489

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

2 x 2 x 2 x 2 x 41 x 17 x 1 x 11 x 489 = 59986608

Therefore, the lowest common multiple of 272,656,451,978 is 59986608.

LCM Formula to Find Lowest Common Multiple of 272,656,451,978

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.

272 x 656 x 451 x 978 = 78702429696

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.

272 : 1, 2, 4, 8, 16, 17, 34, 68, 136, 272

656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656

451 : 1, 11, 41, 451

978 : 1, 2, 3, 6, 163, 326, 489, 978

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 272,656,451,978, is 1.

Now, the common factors can be found like this.

272:2x 2x 2x 2x 17

656:2x 2x 2x 2x 41

451:11x 41

978:2x 3x 163

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 2x 2x 41 = 1312

Therefore, the value for common factors is 1312.

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 = 78702429696/(1x1312)

LCM = 78702429696/1312

LCM = 59986608

Thus, we can understand that the LCM of 272,656,451,978 is 59986608.
