The LCM of 909,690,874,548 is 1088418420.
Find LCM of 909,690,874,548 with Prime Factorization
| 2 | 909, 690, 874, 548 |
| 3 | 909, 345, 437, 274 |
| 23 | 303, 115, 437, 274 |
| 303, 5, 19, 274 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 23 x 303 x 5 x 19 x 274 = 1088418420
Therefore, the lowest common multiple of 909,690,874,548 is 1088418420.
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.
909 x 690 x 874 x 548 = 300403483920
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.
909 : 1, 3, 9, 101, 303, 909
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
874 : 1, 2, 19, 23, 38, 46, 437, 874
548 : 1, 2, 4, 137, 274, 548
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 909,690,874,548, is 1.
Now, the common factors can be found like this.
909:3x 3x 101
690:2x 3x 5x 23
874:2x 19x 23
548:2x 2x 137
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 23 = 276
Therefore, the value for common factors is 276.
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 = 300403483920/(1x276)
LCM = 300403483920/276
LCM = 1088418420
Thus, we can understand that the LCM of 909,690,874,548 is 1088418420.
