Given numbers are 434,711,553,545
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 434,711,553,545 is 168172830.
Find LCM of 434,711,553,545 with Prime Factorization
| 7 | 434, 711, 553, 545 |
| 79 | 62, 711, 79, 545 |
| 62, 9, 1, 545 |
Multiply the prime numbers at the bottom and the left side.
7 x 79 x 62 x 9 x 1 x 545 = 168172830
Therefore, the lowest common multiple of 434,711,553,545 is 168172830.
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.
434 x 711 x 553 x 545 = 92999574990
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.
434 : 1, 2, 7, 14, 31, 62, 217, 434
711 : 1, 3, 9, 79, 237, 711
553 : 1, 7, 79, 553
545 : 1, 5, 109, 545
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 434,711,553,545, is 1.
Now, the common factors can be found like this.
434:2x 7x 31
711:3x 3x 79
553:7x 79
545:5x 109
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 79 = 553
Therefore, the value for common factors is 553.
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 = 92999574990/(1x553)
LCM = 92999574990/553
LCM = 168172830
Thus, we can understand that the LCM of 434,711,553,545 is 168172830.
