Given numbers are 747,706,851,447,684
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 747,706,851,447,684 is 2541117388284.
Find LCM of 747,706,851,447,684 with Prime Factorization
2 | 747, 706, 851, 447, 684 |
3 | 747, 353, 851, 447, 342 |
3 | 249, 353, 851, 149, 114 |
83, 353, 851, 149, 38 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 83 x 353 x 851 x 149 x 38 = 2541117388284
Therefore, the lowest common multiple of 747,706,851,447,684 is 2541117388284.
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.
747 x 706 x 851 x 447 x 684 = 137220338967336
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.
747 : 1, 3, 9, 83, 249, 747
706 : 1, 2, 353, 706
851 : 1, 23, 37, 851
447 : 1, 3, 149, 447
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 747,706,851,447,684, is 1.
Now, the common factors can be found like this.
747:3x 3x 83
706:2x 353
851:23x 37
447:3x 149
684:2x 2x 3x 3x 19
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 3x 3 = 54
Therefore, the value for common factors is 54.
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 = 137220338967336/(1x54)
LCM = 137220338967336/54
LCM = 2541117388284
Thus, we can understand that the LCM of 747,706,851,447,684 is 2541117388284.
