Given numbers are 521,697,697,242
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 521,697,697,242 is 87879154.
Find LCM of 521,697,697,242 with Prime Factorization
17 | 521, 697, 697, 242 |
41 | 521, 41, 41, 242 |
521, 1, 1, 242 |
Multiply the prime numbers at the bottom and the left side.
17 x 41 x 521 x 1 x 1 x 242 = 87879154
Therefore, the lowest common multiple of 521,697,697,242 is 87879154.
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.
521 x 697 x 697 x 242 = 61251770338
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.
521 : 1, 521
697 : 1, 17, 41, 697
697 : 1, 17, 41, 697
242 : 1, 2, 11, 22, 121, 242
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 521,697,697,242, is 1.
Now, the common factors can be found like this.
521:521
697:17x 41
697:17x 41
242:2x 11x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
17x 41 = 697
Therefore, the value for common factors is 697.
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 = 61251770338/(1x697)
LCM = 61251770338/697
LCM = 87879154
Thus, we can understand that the LCM of 521,697,697,242 is 87879154.
