Given numbers are 121,228,684,757
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 121,228,684,757 is 62652348.
Find LCM of 121,228,684,757 with Prime Factorization
2 | 121, 228, 684, 757 |
2 | 121, 114, 342, 757 |
3 | 121, 57, 171, 757 |
19 | 121, 19, 57, 757 |
121, 1, 3, 757 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 19 x 121 x 1 x 3 x 757 = 62652348
Therefore, the lowest common multiple of 121,228,684,757 is 62652348.
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.
121 x 228 x 684 x 757 = 14284735344
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.
121 : 1, 11, 121
228 : 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, 228
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
757 : 1, 757
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,228,684,757, is 1.
Now, the common factors can be found like this.
121:11x 11
228:2x 2x 3x 19
684:2x 2x 3x 3x 19
757:757
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 19 = 228
Therefore, the value for common factors is 228.
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 = 14284735344/(1x228)
LCM = 14284735344/228
LCM = 62652348
Thus, we can understand that the LCM of 121,228,684,757 is 62652348.
