Given numbers are 747,861,412,697,447
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 747,861,412,697,447 is 223735502844.
Find LCM of 747,861,412,697,447 with Prime Factorization
3 | 747, 861, 412, 697, 447 |
41 | 249, 287, 412, 697, 149 |
249, 7, 412, 17, 149 |
Multiply the prime numbers at the bottom and the left side.
3 x 41 x 249 x 7 x 412 x 17 x 149 = 223735502844
Therefore, the lowest common multiple of 747,861,412,697,447 is 223735502844.
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 861 x 412 x 697 x 447 = 82558400549436
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
861 : 1, 3, 7, 21, 41, 123, 287, 861
412 : 1, 2, 4, 103, 206, 412
697 : 1, 17, 41, 697
447 : 1, 3, 149, 447
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 747,861,412,697,447, is 1.
Now, the common factors can be found like this.
747:3x 3x 83
861:3x 7x 41
412:2x 2x 103
697:17x 41
447:3x 149
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 41 = 369
Therefore, the value for common factors is 369.
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 = 82558400549436/(1x369)
LCM = 82558400549436/369
LCM = 223735502844
Thus, we can understand that the LCM of 747,861,412,697,447 is 223735502844.
