Given numbers are 7,493,221,441
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 7,493,221,441 is 2826369.
Find LCM of 7,493,221,441 with Prime Factorization
7 | 7, 493, 221, 441 |
17 | 1, 493, 221, 63 |
1, 29, 13, 63 |
Multiply the prime numbers at the bottom and the left side.
7 x 17 x 1 x 29 x 13 x 63 = 2826369
Therefore, the lowest common multiple of 7,493,221,441 is 2826369.
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.
7 x 493 x 221 x 441 = 336337911
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.
7 : 1, 7
493 : 1, 17, 29, 493
221 : 1, 13, 17, 221
441 : 1, 3, 7, 9, 21, 49, 63, 147, 441
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 7,493,221,441, is 1.
Now, the common factors can be found like this.
7:7
493:17x 29
221:13x 17
441:3x 3x 7x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 17 = 119
Therefore, the value for common factors is 119.
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 = 336337911/(1x119)
LCM = 336337911/119
LCM = 2826369
Thus, we can understand that the LCM of 7,493,221,441 is 2826369.
