Given numbers are 689,451,242,711,672
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 689,451,242,711,672 is 544384897056.
Find LCM of 689,451,242,711,672 with Prime Factorization
| 2 | 689, 451, 242, 711, 672 |
| 3 | 689, 451, 121, 711, 336 |
| 11 | 689, 451, 121, 237, 112 |
| 689, 41, 11, 237, 112 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 689 x 41 x 11 x 237 x 112 = 544384897056
Therefore, the lowest common multiple of 689,451,242,711,672 is 544384897056.
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.
689 x 451 x 242 x 711 x 672 = 35929403205696
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.
689 : 1, 13, 53, 689
451 : 1, 11, 41, 451
242 : 1, 2, 11, 22, 121, 242
711 : 1, 3, 9, 79, 237, 711
672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,451,242,711,672, is 1.
Now, the common factors can be found like this.
689:13x 53
451:11x 41
242:2x 11x 11
711:3x 3x 79
672:2x 2x 2x 2x 2x 3x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 11 = 66
Therefore, the value for common factors is 66.
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 = 35929403205696/(1x66)
LCM = 35929403205696/66
LCM = 544384897056
Thus, we can understand that the LCM of 689,451,242,711,672 is 544384897056.
